ARM: imx: imx8m: Introduce and use UART_BASE_ADDR(n)
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base address. Convert all board configurations to this new macro. This is the first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a clean up, no functional change. The new macro contains compile-time test to verify N is in suitable range. The test works such that it multiplies constant N by constant double-negation of size of a non-empty structure, i.e. it multiplies constant N by constant 1 in each successful compilation case. The non-empty structure may contain C11 _Static_assert(), make use of this and place the kernel variant of static assert in there, so that it performs the compile-time check for N in the correct range. Note that it is not possible to directly use static_assert in compound statements, hence this convoluted construct.
