MIPS: rzx50: prepare for new debug_ll

Set DEBUG_LL_UART_DIVISOR to use <asm/debug_ll_ns16550.h>.

The JZ4755 uses 24 MHz as the main reference frequency (EXCLK).
The UART controller can work on full EXCLK or on EXCLK/2.
Just now we use EXCLK/2 legacy clock setup made by U-Boot.
So set UART controller base frequency to 12 MHz.

MIPS: unify ns16550 debug_ll support code

This commit moves the C debug_ll code from
the MIPS <debug_ll_ns16550.h> header file to
the MIPS <asm/debug_ll_ns16550.h> header file,
so the C code and the asm code can use the same
register address macros.

MIPS: rzx50_defconfig: use UART1 for low-level debug

By default CONFIG_JZ4750D_DEBUG_LL_UART0 is selected.
This can confuse the Ritmix RZX50 user as the board
has only UART1 connected.
