[U-Boot-Users] [PATCH] fix taihu soft spi_read

[Markus Brunner]

The taihu board used gpio_read_out_bit which reads the output register and not 
the pin state.

The function gpio_read_out_bit didn't exist in u-boot <= 1.3.1 so every usage 
of gpio_read_out_bit deserves a closer look.

Applied to u-boot-ppc4xx custodian repository. Will get pulled into 1.3.2
