[PATCH 1/2] irqchip/ti-sci: Simplify with dev_err_probe()

[Krzysztof Kozlowski]

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and the error value gets printed.

There is also no need to assign NULL to 'intr->sci' as it is part of
devm-allocated memory.
