[PATCH v1 1/3] blackfin: Enable early print via the generic serial API.

From: Sonic Zhang <sonic.zhang@...>

Remove blackfin specific implementation of the generic serial API when
early print macro is defined.

In BFIN_BOOT_BYPASS mode, don't call generic serial_puts, because
early print in bypass mode is running before code binary is relocated
to the link address.

[PATCH v1 1/2] bfin: Remove spi dma function in bf5xx.

From: Scott Jiang <scott.jiang.linux@...>

BF5xx rx dma causes spi flash random read error.
Accually spi controller has problems both on tx and rx dma.
So remove spi dma support in u-boot.

[PATCH v1 1/2] blackfin: Set correct early debug serial baudrate.

From: Sonic Zhang <sonic.zhang@...>

Calculate the early uart clock from the system clock registers set by
the bootrom other than the predefine uboot clock macros.

Split the early baudrate setting function and the normal baudrate
setting one.
