The Snapdragon 670 uses the RPMh mailbox for most of the clocks used in
SDM845 but omits two. Add clock data for SDM670 so the driver doesn't fail
to resolve a clock.

While fixing up the driver I noticed that my IPQ8074 board was hanging
after CPUFreq switched the frequency during boot, WDT would eventually
reset it.
So mark apcs_alias0_core_clk as critical since its the clock feeding the
CPU cluster and must never be disabled.

While working on IPQ8074 APSS driver it was discovered that IPQ6018 and
IPQ8074 use almost the same PLL and APSS clocks, however APSS driver is
currently broken.
More precisely apcs_alias0_clk_src is broken, it was added as regmap_mux
clock.
However after debugging why it was always stuck at 800Mhz, it was figured
out that its not regmap_mux compatible at all.
It is a simple mux but it uses RCG2 register layout and control bits, so
utilize the new clk_rcg2_mux_closest_ops to correctly drive it while not
having to provide a dummy frequency table.
While we are here, use ARRAY_SIZE for number of parents.
Tested on IPQ6018-CP01-C1 reference board and multiple IPQ8074 boards.

An RCG may act as a mux that switch between 2 parents.
This is the case on IPQ6018 and IPQ8074 where the APCS core clk that feeds
the CPU cluster clock just switches between XO and the PLL that feeds it.
Add the required ops to add support for this special configuration and use
the generic mux function to determine the rate.
This way we dont have to keep a essentially dummy frequency table to use
RCG2 as a mux.

The USB PHY on MSM8909 works with the driver used on MSM8916
(phy-qcom-usb-hs.c). When turning the PHY on/off it is first reset
using the standard reset controller API. On MSM8916 the reset is
provided by the USB driver (ci_hdrc_msm_por_reset() in ci_hdrc_msm.c).
While this seems to work on MSM8909 as well, the Qualcomm Linux sources
suggest that the PHY should be reset using the GCC_USB2_HS_PHY_ONLY_BCR
register instead. In general this is easy to set up in the device tree,
thanks to the standard reset controller API.
However, to conform to the specifications of the PHY the reset signal
should be asserted for at least 10 us. This is handled correctly on
MSM8916 in ci_hdrc_msm_por_reset(), but not within the GCC driver.
Fix this by making use of the new "udelay" field of qcom_reset_map
and set a delay of ~15 us between the assertion/deassertion of the
USB PHY reset signal.

The amount of time required between asserting and deasserting the reset
signal can vary depending on the involved hardware component. Sometimes
1 us might not be enough and a larger delay is necessary to conform to
the specifications.
Usually this is worked around in the consuming drivers, by replacing
reset_control_reset() with a sequence of reset_control_assert(), waiting
for a custom delay, followed by reset_control_deassert().
However, in some cases the driver making use of the reset is generic and
can be used with different reset controllers. In this case the reset
time requirement is better handled directly by the reset controller
driver.
Make this possible by adding an "udelay" field to the qcom_reset_map
that allows setting a different reset delay (in microseconds).
