Since PM_READ(reg) expands to readl(power->base + (reg)), the expression: PM_READ(PM_GRAFX & PM_V3DRSTN) computes the bitwise AND of the register offset PM_GRAFX with the bitmask PM_V3DRSTN before using the result as a register offset, reading from the wrong MMIO address instead of the intended PM_GRAFX register. The same issue affects the PM_IMAGE cases. Fix by moving the closing parenthesis so PM_READ() receives only the register offset, and the bitmask is applied to the value returned by the read.
