Since the clocksource framework has the support for suspend time
compensation. Re-work the driver to use that, so we can reduce the
duplicate code.

Add support for the Tegra210 timer that runs at oscillator clock
(TMR10-TMR13). We need these timers to work as clock event device and to
replace the ARMv8 architected timer due to it can't survive across the
power cycle of the CPU core or CPUPORESET signal. So it can't be a wake-up
source when CPU suspends in power down state.
Also convert the original driver to use timer-of API.

In order to unify the names in this directory, let's rename the driver to be
prefixed with timer-*
