ARM: HYP/non-sec: Fix the ARCH Timer frequency setting.
For some SoCs, the system clock frequency may not equal to the
ARCH Timer's frequency.
This patch uses the CONFIG_TIMER_CLK_FREQ instead of
CONFIG_SYS_CLK_FREQ, then the system clock macro and arch timer
macor could be set separately and without interfering each other.
