[PATCH v3 07/16] ArmPlatformPkg: PL111Lcd: Combine two writes to LCDControl

[Girish Pathak <girish.pathak@arm.com>]

Currenty bit LcdPwr of the LCDControl register is enabled immediately
after setting other bits of the LCDControl register. This two write
sequence is unnecessary. This change removes this extra write by setting
LcdPwr bit along with other bits of the LcdControl register.
