clocksource/drivers/arm_arch_timer: Fix CNTPCT_LO and CNTVCT_LO value
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
