pinctrl: renesas: rzv2m: Handle non-unique subnode names
The eMMC and SDHI pin control configuration nodes in DT have subnodes
with the same names ("data" and "ctrl"). As the RZ/V2M pin control
driver considers only the names of the subnodes, this leads to
conflicts:
pinctrl-rzv2m b6250000.pinctrl: pin P8_2 already requested by 85000000.mmc; cannot claim for 85020000.mmc
pinctrl-rzv2m b6250000.pinctrl: pin-130 (85020000.mmc) status -22
renesas_sdhi_internal_dmac 85020000.mmc: Error applying setting, reverse things back
Fix this by constructing unique names from the node names of both the
pin control configuration node and its child node, where appropriate.
