ArmPlatformPkg/PL011UartLib : Fix incorrect control bit validation
REF: [e092122]
(PR #12085)
The current logic in ArmPlatformPkg/PL011UartLib performs
control-bit checks intended to align with the UEFI specification.
However, it incorrectly validates control bits that
cannot be set through SetControl(), resulting in failures
in the SetControl() SCT test.
According to the UEFI specification,
the valid control bits that can be set are:
EFI_SERIAL_REQUEST_TO_SEND
EFI_SERIAL_DATA_TERMINAL_READY
EFI_SERIAL_HARDWARE_LOOPBACK_ENABLE
EFI_SERIAL_SOFTWARE_LOOPBACK_ENABLE
EFI_SERIAL_HARDWARE_FLOW_CONTROL_ENABLE
This patch updates mAllowedControlBits so that only these
valid control bits are accepted during validation.
