realtek_mst_i2c_spi.c: Update write protection toggle function

The write protection trigger has been updated by the vendor so update
here as well. Basically the idea is to push the GPIO pin for write
protectoin to low or high. The process would be 1. write to GPIO
configuration register to enable write protection pin value update.
2. write to GPIO data register to toggle the actual protection pin
value.

BUG=b:152558985,b:148745673
BRANCH=none
TEST=builds && verified the write protection get disabled.
