mb/google/nissa/var/glassway: Modify touch screen ILIT2901 sequence

After modified the settings, it could be met the time sequence for
this ILIT2901 touchscreen specification via our EE's measurements.
1. We will request vendor to update F/W, which delay calibration timing.
2. Double delay RST time to 12ms.
3. F/W calibration delay time is about 700ms after RST high.
   The tuned firmware version is 005c_0700.0000.0000.0006.bin.

BUG=b:375986645
BRANCH=firmware-nissa-15217.B
TEST=1. emerge-nissa coreboot chromeos-bootimage
     2. Verified the sequence correctly by EE.
