All uniphier v7 SoCs have cortex-a9 and use cortex-a9 global timer
in a simple implementation. Now DM_TIMER of it is available
on 35751c7f3f ("timer: sti: convert sti-timer to arm a9 global timer"),
so let's switch to it.
The old driver reads the lower 32bits of counter field
and sets the prescaler as 50 with PERIPHCLK(=50MHz),
so the global timer works as a 32-bit 1MHz timer.
The DM_TIMER uses the whole 64bits with no prescaler,
so the global timer works as a 64-bit PERIPHCLK timer.
CONFIG_SYS_HZ_CLOCK is set as the default PERIPHCLK frequency,
if there is no 'clocks' property in devicetree.
