Input: hideep - silence error in SW_RESET()

On some models the first HIDEEP_SYSCON_WDT_CON write alone is enough to
cause the controller to reset, causing the second write to fail:

i2c-hideep_ts: write to register 0x52000014 (0x000001) failed: -121

Switch this write to a raw hideep_pgm_w_mem() to avoid an error getting
logged in this case.
