soc: qcom: llcc: ioremap resource only when multi_ch_reg exists

Browse Source 
Since not all the platforms have multi_ch_reg, the usage of
devm_platform_ioremap_resource_byname will cause "invalid resource"
error, split it and ioremap resource only when multi_ch_reg exists
to avoid the error message.
