This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs. Ends up adding only ~512bytes per additional UART.

This creates a standalone ELF that executes just the Blackfin initcode. This is useful for people who want to program the low level aspects of the CPU (memory/clocks/etc...) and can easily be used with JTAG for quick booting while developing.

These boards have an mmc/sd slot on them connected over SPI, so enable the driver.

We really only need to tweak the async banks in the initcode if the processor is booting out of it, otherwise we can wait until later on in the CPU booting setup.

This also makes testing in the sim and early bring up over JTAG work much smoother when the initcode gets bypassed.

Rewrite the assembly serial_early_puts() helper to place the strings in the .rodata section rather than embedding them directly in the .text section. Using .text is a little simpler, but it doesn't let people execute out of internal L1 sram (since core reads don't work on those regions).
