Simon Horman f61831ee61 ARM: mach-shmobile: ap4evb, mackerel: fixup scif initialisation for zboot
* Set receive enable and transmit enable bits of SCASCR0 (E6C400089).
  Values previously written to this register was bogus.

  Curiously earlyprintk works with the previous code.

* Remove duplicate initialisation of GPIO port 152, SCIFA0_TXD (0xE6053098).
  This should have no effect other than to very slightly reduce the amount of
  code.

Simon Horman 38915d2e9e ARM: mach-shmobile: mackerel: SCIF port for earlyprintk when using zboot
Initialise the SCIF serial port to allow earlyprintk
output when using zboot. It is based on a very similar
patched for AP4EB.

When CONFIG_ZBOOT_ROM is selected, the resulting zImage file will be small
boot loader and may be burned to rom or flash.
