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.
