[PATCH] irqchip/qcom-pdc: fix linking against QCOM_SCM firmware

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Build testing with SCM disabled or in a loadable module fails
with a link error:

s390-linux-ld: drivers/irqchip/qcom-pdc.o: in function `qcom_pdc_probe':
qcom-pdc.c:(.text+0x18b8): undefined reference to `qcom_scm_is_available'
qcom-pdc.c:(.text+0x18ce): undefined reference to `qcom_scm_io_writel'

As QCOM_SCM can already be enabled for compile testing on non-qualcomm
machines, but is always enabled on Qualcomm Arm kernels, use that
as the Kconfig dependency and remove the ||COMPILE_TEST check.

Fixes: 1b852de05f74 ("irqchip/qcom: Enable compile testing for QCOM_PDC and QCOM_MPM")
Fixes: ad01c2b2f291 ("irqchip/qcom-pdc: Configure PDC to pass through mode")
