The interrupt handler routines and helpers are casting the 'void *'
pointer to 'struct exynos_uart_port *' all over the place.
There is no need for that, we can do the casting once and keep passing
the 'struct exynos_uart_port *', simplifying the code and saving a few
lines of code.
No functional changes.
