linux-kirkwood: fixed patch issues for openrd-base

- eliminate a patch from the recipe that was already in git
- fixed a patch which failed on a file which was not applicable for openrd-base
  (made a dedicated patch with only those parts that are needed for openrd-base)

+Subject: [PATCH] ARM: Kirkwood: OpenRD: SD/UART1 selection
+
+To select UART1, pass "uart=232" (for RS232) OR "uart=485" (for RS485) in the
+boot argument. To select SDIO lines pass "uart=no". SDIO lines will be selected
+by default in absence of this parameter.
