spi: pxa2xx: Add missed security checks
[ Upstream commit 5eb263ef08
]
pxa2xx_spi_init_pdata misses checks for devm_clk_get and
platform_get_irq.
Add checks for them to fix the bugs.
Since ssp->clk and ssp->irq are used in probe, they are mandatory here.
So we cannot use _optional() for devm_clk_get and platform_get_irq.
