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

Browse source 
After modified the settings, it could be met the time sequence for
this ILIT2901 touchscreen specification via our EE's measurements.
1. ILIT2901 Specification: ILI2901A-A202 Data Sheet_V1.2_20240128.pdf.
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.
