Gustavo A. R. Silva 9965da064e usb: typec: Fix unchecked return value

[ Upstream commit e82adc1074 ]

Currently there is no check on platform_get_irq() return value
in case it fails, hence never actually reporting any errors and
causing unexpected behavior when using such value as argument
for function regmap_irq_get_virq().

Fix this by adding a proper check, a message error and return
*irq* in case platform_get_irq() fails.

Addresses-Coverity-ID: 1443899 ("Improper use of negative value")
Fixes: d2061f9cc3 ("usb: typec: add driver for Intel Whiskey Cove PMIC USB Type-C PHY")
