 *
 * FUNCTION:    AcpiReadBitRegister
 *
 * PARAMETERS:  RegisterId      - ID of ACPI Bit Register to access
 *              ReturnValue     - Value that was read from the register,
 *                                normalized to bit position zero.
 *
 * RETURN:      Status and the value read from the specified Register. Value
 *              returned is normalized to bit0 (is shifted all the way right)
 *
 * DESCRIPTION: ACPI BitRegister read function. Does not acquire the HW lock.
 *
 * SUPPORTS:    Bit fields in PM1 Status, PM1 Enable, PM1 Control, and
 *              PM2 Control.
 *
 * Note: The hardware lock is not required when reading the ACPI bit registers
 *       since almost all of them are single bit and it does not matter that
 *       the parent hardware register can be split across two physical
 *       registers. The only multi-bit field is SLP_TYP in the PM1 control
 *       register, but this field does not cross an 8-bit boundary (nor does
 *       it make much sense to actually read this field.)
