fwk: cypd: increase the cypd stack size to 1280

When I used the console command "i2ctrace enable 2 0x40", the EC
log print the panic message:

ec:~> i2ctrace enable 2 0x40
i2c: 2:0x40 wr 0x06 0x00   rd 0x04

This change increases the cypd stack size to 1280 to avoid the
stack overflow.

BRANCH=fwk-main
BUG=enable pd chip i2ctrace will trigger the stack overflow
TEST=i2ctrace enable 2 0x40 can trace the i2c log normally
