perf: fsl_imx8_ddr: Add AXI ID PORT CHANNEL filter support

This is the extension of AXI ID filter.

Filter is defined with 2 configuration registers per counter 1-3 (counter
0 is not used for filtering and lacks these registers).
* Counter N MASK COMP register - AXI_ID and AXI_MASKING.
* Counter N MUX CNTL register - AXI CHANNEL and AXI PORT.
  -- 0: address channel
  -- 1: data channel

This filter is exposed to userspace as an additional (channel, port) pair.
The definition of axi_channel is inverted in userspace, and it will be
reverted in driver automatically.

AXI filter of Perf Monitor in DDR Subsystem, only a single port0 exist, so
axi_port is reserved which should be 0.

e.g.
perf stat -a -e imx8_ddr0/axid-read,axi_mask=0xMMMM,axi_id=0xDDDD,axi_channel=0xH/ cmd
perf stat -a -e imx8_ddr0/axid-write,axi_mask=0xMMMM,axi_id=0xDDDD,axi_channel=0xH/ cmd
