[U-Boot] [PATCH 1/2] armv8: ls1028a: configure PMU's PCTBENR to enable WDT

From: Thomas Schaefer <thomas.schaefer at kontron.com>

The SP805-WDT module on LS1028A requires configuration of PMU's
PCTBENR register to enable watchdog counter decrement and reset
signal generation. The watchdog clock needs to be enabled first.
