[U-Boot] [PATCH v2 0/2] drivers: timer: inroduce ARC timer driver

[Vlad Zakharov]

This patch series replaces legacy approach to access ARC timer
via specific code in "arch/arc/lib/time.c" and uses timer
driver instead.

ARC cores may have up to 2 built-in timers: timer0 and timer1,
usually at least one of them exists.

They are controlled through auxiliary registers and so we
don't have to remap their control registers as we used to do
with MMIO registers of external peripheral devices.

arch Kconfig file to avoid duplication
