spi/pxa2xx: fix runtime PM enabling order

In commit 0628ddf4217bcfc30ce2bb5587b3e376eb332780 (spi/pxa2xx: Convert
to core runtime PM) master->auto_runtime_pm was set to true.

In this case pm_runtime_enable() must be called *before*
spi_register_master(), otherwise the kernel hangs with this error
message:

  spi_master spi0: Failed to power device: -13

A similar fix, but for spi/hspi, was applied in
790f795a555c11ddbb829a3a7a46e8e46b194f78.
