spi/hspi: fixup Runtime PM enable timing

Browse source 
3e00a09d2f
(spi/hspi: Convert to core runtime PM)
enabled master->auto_runtime_pm.
Then, pm_runtime_enable() is required *before*
spi_register_master() calling.
This patch fixed it up.
Kernel will hang up with "spi_master spi0: Failed to power device: -13"
message without this patch.
