coresight: Extend the PIDR mask to cover relevant bits in PIDR2
As per coresight standards, PIDR2 register has the following format :
[2-0] - JEP106_bits6to4
[3] - JEDEC, designer ID is specified by JEDEC.
However some of the drivers only use mask of 0x3 for the PIDR2 leaving
bits [3-2] unchecked, which could potentially match the component for
a different device altogether. This patch fixes the mask and the
corresponding id bits for the existing devices.
