Currently, when a single channel's brightness is set, and then cleared
to zero subsequently, the LED stays on instead of getting turned off
because symmetrical brightness distribution logic does not allow the
paired channel's brightness to be set to zero. Fix this.
It was also observed that the brightness of a channel that is getting
turned off doesn't show up as zero, so fix that as well.
In addition, strengthen error-checking of the "qcom,led-mask" device
tree property.

Set saved cmac on ioctl from user space.
Write saved cmac to shared memory on SSR.
Read calculated cmac from shared memory.
Provide calculated cmac to user space via sysfs.
Cleanup unused IAR-STATE fuses.
Cleanup unused IAR-FEATURE-ENABLED fuse.
Read actual PIL area size from register.
pbl_cmac_show() returns binary rather than string.
Change IOCTL to use variable-size-array.

each register contain one parameter,
there is no need to read register before write,
it can improve time when change a mode.

Due to a race condition between the probe and glink message
callback, it is observed that the glink messages/notifications
can be handled even after the probe failure which leads to
an invalid memory access. Fix it by introducing "initialized"
flag. While at it, add few error logs to identify the exact
message failures.

currently when power up with no usb cable, chip only disable
when system enter suspend state, disable chip during probe
will consume lower power early.
another fix is no need to disable chip again for suspend operation.

In certain devices, LED channels are paired and connected to two
separate LEDs. Due to symmetrical configuration, a switch that controls
all four channels sets the same brightness value to both LEDs, which is
not the intended behaviour; hence, handle this case separately.
E.g. If flash0 (group 1) is set to 144 and flash1 (group 2) is set to
1056, current will be distributed evenly to all 4 channels like so: 300
mA would be set on all channels (as 144 + 1056 = 1200; 1200 / 4 = 300).
Change this to:
144 / 2 = 72 on channels 0 and 3 (group 1)
1056 / 2 = 528 on channels 1 and 2 (group 2).

restarts (PDR), resend the ICL/FCC votes from clients like USB
