Use c99 initializers for structures.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@decl@
identifier i1,fld;
type T;
field list[n] fs;
@@
struct i1 {
fs
T fld;
...};
@bad@
identifier decl.i1,i2;
expression e;
initializer list[decl.n] is;
@@
struct i1 i2 = { is,
+ .fld = e
- e
,...};
// </smpl>

[thierry.reding: rebased and applied same fix for Braswell]

An x86 build seems to pull in the linux/io.h include indirectly. On
PowerPC that doesn't happen and the build breaks due to the readl() and
writel() functions not being declared. Fix this by explicitly including
linux/io.h.

The driver consists of core, PCI, and platform parts. It would be better
to split them into separate files.
The platform driver is now called pwm-lpss-platform. Thus, previously
set CONFIG_PWM_LPSS=m is not enough to build it. But we are on the safe
side since it seems no one from outside Intel is using it for now.
While here, move to use macros module_pci_driver() and
module_platform_driver().

This is pretty much the same as Baytrail PWM. Only difference is that the
input clock runs on different frequency.

Unlike other Intel LPSS devices, the PWM does not have the
clock dividers or the gate. All we get from the clock is the
rate. Since PCI case uses the driver data to get the rate,
we can drop the clk and use the same data also in case of
ACPI. The frequency is the same.

Not all systems enumerate the PWM devices via ACPI. They can also be
exposed via the PCI interface.
