[PATCH 6.1 0026/1146] soc: qcom: llcc: make irq truly optional

From: Luca Weiss <luca.weiss@fairphone.com>

[ Upstream commit c882c899ead3545102a4d71b5fbe73b9e4bc2657 ]

The function platform_get_irq prints an error message into the kernel
log when the irq isn't found.

Since the interrupt is actually optional and not provided by some SoCs,
use platform_get_irq_optional which does not print an error message.
