soc: qcom: pd-mapper: mark qcom_pdm_domains as __maybe_unused

Browse Source 
The qcom_pdm_domains[] array is used only when passing it into of_match_node()
but is not also referenced by MODULE_DEVICE_TABLE() or the platform driver
as a table. When CONFIG_OF is disabled, this causes a harmless build warning:

drivers/soc/qcom/qcom_pd_mapper.c:520:34: error: 'qcom_pdm_domains' defined but not used [-Werror=unused-const-variable=]

Avoid this by marking the variable as __maybe_unused. This also makes it
clear that anything referenced by it will be dropped by the compiler when
it is unused.
