[PATCH] input synaptics-rmi4 trivial: rmi_driver.c tidy-up

[Christopher Heiny <cheiny@synaptics.com>]

This has three trivial changes:

1) multi-line commenting is changed to kernel coding standard

2) reset_and_reflash() function is renamed to rmi_initial_reset() and
recommentedto reflect what it actually does.

3) #endif comment was updated to actuall match the opening #if CONFIG_PM_SLEEP
condition.
