arm: omap5+: Add support for early debug
For early debug, the following configs needs to be enabled:
CONFIG_DEBUG_UART=y
CONFIG_DEBUG_UART_OMAP=y
CONFIG_DEBUG_UART_CLOCK=48000000
CONFIG_DEBUG_UART_SHIFT=2
CONFIG_DEBUG_UART_ANNOUNCE=y
For DRA7xx:
CONFIG_DEBUG_UART_BASE=0x4806a000
For AM57xx:
CONFIG_DEBUG_UART_BASE=0x48020000
