For the rest of the iterations, call reinit_completion() instead.

87917528cc spi: bcm63xx-hsspi: checking for ERR_PTR instead of NULL 
devm_request_and_ioremap() returns NULL on error, it doesn't return an
ERR_PTR().  This patch fixes it by switching to devm_ioremap_resource()
which is the prefered function anyway.

Add a driver for the High Speed SPI controller found on newer BCM63XX SoCs.

It does feature some new modes like 3-wire or dual spi, but neither of it
is currently implemented.
