coresight: etmv4: Fix ETMv4x peripheral ID table
This patch cleans up the peripheral id table for different ETMv4 implementations. As per Cortex-A53 TRM, the ETM has following id values: Peripheral ID0 0x5D 0xFE0 Peripheral ID1 0xB9 0xFE4 Peripheral ID2 0x4B 0xFE8 Peripheral ID3 0x00 0xFEC where, PID2: has the following format: [7:4] Revision [3] JEDEC 0b1 res1. Indicates a JEP106 identity code is used [2:0] DES_1 0b011 ARM Limited. This is bits[6:4] of JEP106 ID code The existing table entry checks only the bits [1:0], which is not sufficient enough. Fix it to match bits [3:0], just like the other entries do. While at it, correct the comment for A57 and the A53 entry.
