The device tree code checks for the presence of a reset driver and calls
the of_reset function pointer by looking up the reset driver as a module.

ACPI defines _RST method to perform device level reset. After the _RST
method is executed, the OS can resume using the device.

This patch checks the presence of _RST method and calls the _RST
method when reset is requested.

Changes:
1. No functional changes. Just divide the patches into subpatches for easy
