servo_v4: Remove PSTATE to create more space in RO

Browse Source 
When including USB PD support, the image won't fit in the default RO
size of 0xf000, but does fit in the 0x10000 RW. This change removes
PSTATE and increases the RO to 0x10000.

BRANCH=none
BUG=chrome-os-partner:61170
TEST=manual
Verfied the image still builds and can run after updating via
util/flash_ec and via /usb_updater/fw_update.py -b servo_v4.json
