The resulting code is way more readeable and intuitive compared to plain
list_for_each.

This patch exposes backlight control into userspace by creating a
backlight device instead of directly accessing the PWM registers.
The backlight driver can't go on a separate file as it shares the I2C
bus & address with the panel.

rid of vchiq_killable.h. I took into account Arnd's commit to avoid
merge conflicts.

vchi_killable.h overrides down_interruptible() by implementing a
function similar to down_killable(). To make things simpler we turn
calls to down_interruptible() into kernel's implementation of
down_killable().

Some operations performed in the probe function should have been
implemented in the init function. Namely class and dev region creations.

Both functions checked the minor number of the cdev prior running the
code. This was useless since the number of devices is already limited by
alloc_chrdev_region.
This removes the check and reindents the code where relevant.

We update sync to reflect that the firmware version is compatible with
that option. We don't need to check both of them again further down the
code.

vchiq_init_state() initialises a series of semaphores to then call
remote_event_create() on the same semaphores, which initializes them
again.

All the memory operations featured in this file modify/access memory
that is only accessed by the CPU. So we can assume that all the memory
barrier handling done by the completion routines is good enough for us.
