The Broadcom pcie setup has a devicetree dependency like:
/pcie/paxdma -> /pcie/pcie -> /soc/pl330
Add a separate init symbol for iproc_pax_v2 so that these gets
initialized in order, fixes this error:
$ west build -p -b bcm958402m2_m7 tests/kernel/common \
-DCONFIG_CHECK_INIT_PRIORITIES=y

Update DMA drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.
