CNTPCT_LO and CNTVCT_LO are defined by mistake in commit '8b82c4f883a7',
so fix them according to the Arm ARM DDI 0487I.a, Table I2-4
"CNTBaseN memory map" as follows:

Offset    Register      Type Description
0x000     CNTPCT[31:0]  RO   Physical Count register.
0x004     CNTPCT[63:32] RO
0x008     CNTVCT[31:0]  RO   Virtual Count register.
0x00C     CNTVCT[63:32] RO
