qcs405: Implement bitbang UART for bootblock

This patch replaces the UART in the bootblock of QCS405 with a bitbang
implementation. Since QCS405 hardware UART needs a firmware blob loaded
into it before it becomes usable, it is not really suited for use in the
bootblock (since by the time we can read blobs from SPI, the bootblock
is essentially over anyway). This solution allows us to still have some
console output during early SoC initialization.
