    exynos5250: add missing address-of operator in UART driver
    
    This adds a missing address-of operator. This was a subtle bug that
    didn't seem to cause problems at first since the serial console
    appeared to work. However it caused an imprecise external abort which
    became apparent later on when aborts were unmasked in the kernel via
    the CPSR_A bit.
    
    (credit goes to Gabe Black for finding this)
