We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver.
Note that we no longer need ti,no-reset-on-init as the rstctrl resets
are properly handled by the reset driver and claimed by the RTC driver.
And we need to squash together the module ranges for driver compability.

To drop the legacy platform data for am3 control module, we need
to configure the missing functional clock and tag the module to
not idle as platform data also had it configured with
HWMOD_INIT_NO_IDLE.

We now manage clocksource and clockevent clocks directly with
timer-ti-dm-systimer. In order to use genpd with prm_omap,
GENPD_FLAG_PM_CLK and simple-pm-bus, we need to keep the system
timer related interconnect clocks enabled until clocksource suspend
is done.

In order for suspend and resume to work with genpd on am4, we must keep
l3 main clock always on. Otherwise prm_omap driver will shut down the l3
main clock on suspend when simple-pm-bus and GENPD_FLAG_PM_CLK are used.
Note that we already keep the l3 main clock always on with the legacy
platform code.
Later on we may want to start managing the l3 main clock with a dedicated
interconnect driver instead of using simple-pm-bus and GENPD_FLAG_PM_CLK.

In order to move wkup_m3 to probe without platform data, let's add
support for using optional reset control driver if configured in the
dts. With this change and the related dts change, we can start
dropping the platform data for am335x.
And once wkup_m3 no longer needs platform data, we can simply drop the
related legacy reset platform data callbacks from wkup_m3 driver later
on after also am437x no longer depends on it.

The rstctrl reset must be asserted after gating the module clock as
described in the TRM at least for IVA. Otherwise the rstctrl reset
done with module clock enabled can hang the system.
Note that this issue is has been only seen with related IVA changes
that we do not currently have merged. So probably no need to apply
this patch as a fix.

Bail out early from sysc_wait_softreset() just like we do in sysc_reset()
if there's no sysstatus srst_shift to fix a bogus resetdone warning on
enable as suggested by Grygorii Strashko <[email protected]>.
We do not currently handle resets for modules that need writing to the
sysstatus register. If we at some point add that, we also need to add
SYSS_QUIRK_RESETDONE_INVERTED flag for cpsw as the sysstatus bit is low
when reset is done as described in the am335x TRM "Table 14-202
SOFT_RESET Register Field Descriptions"

Commit d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and
wait for softreset bit") started showing a "OCP softreset timed out"
warning on enable if the interconnect target module is not out of reset.
This caused the warning to be often triggered for i2c and hdq while the
devices are working properly.
Turns out that some interconnect target modules seem to have an unusable
reset status bits unless the module specific reset quirks are activated.
Let's just skip the reset status check for those modules as we only want
to activate the reset quirks when doing a reset, and not on enable. This
way we don't see the bogus "OCP softreset timed out" warnings during boot.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.
Conversion done using the script at:

Commit 453431a54934 ("mm, treewide: rename kzfree() to
kfree_sensitive()") renamed kzfree() to kfree_sensitive(),
but it left a compatibility definition of kzfree() to avoid
being too disruptive.
Since then a few more instances of kzfree() have slipped in.
Just get rid of them and remove the compatibility definition
once and for all.
