When the touch controller firmware is upgraded, the config data on
the controller might require an update too to match the firmware.
Since the driver performs config version checking before updating
config data and only updates to a newer version, we need to zero
out the config version after a firmware upgrade to make sure proper
config data will be programmed to the touch controller.

Currently during boot, and every suspend/resume, we call

some regulators don't support this function, and this will cause
set_optimum_mode to print an error when this occures. Correct this by
checking if it is valid to call set_optimum_mode on a given regulator
before doing so.
