clocksource/drivers/timer-tegra186: Fix support for multiple watchdog instances
Tegra SoCs support multiple watchdogs; currently only one (WDT0) is
used. When multiple watchdogs are registered, tegra186_wdt_enable()
overwrites the TKEIE(x) register, discarding any existing watchdog
interrupt enable bits. As a result, enabling one watchdog inadvertently
disables interrupts for the others.
Fix this by preserving the existing TKEIE(x) value and updating it
using a read-modify-write sequence.
