pinctrl: tegra: avoid duplicate field initializers

The drv_reg field is initialized both in the DRV_PINGROUP_ENTRY_N/DRV_PINGROUP_ENTRY_Y
macros and in DRV_PINGROUP_Y. Since each pingroup expands both macros, the are
always duplicate and turning on -Woverride-init (which is disabled by default)
causes a huge amount of warnings like:

drivers/pinctrl/tegra/pinctrl-tegra234.c:1384:27: error: initialized field overwritten [-Werror=override-init]
 1384 | #define DRV_PINGROUP_Y(r) ((r))
      |                           ^

 1397 |                 .drv_reg = DRV_PINGROUP_Y(r),                   \
      |                            ^~~~~~~~~~~~~~

      |                                                 ^~~~~~~~~~~~~~~~~~~~
...

Remove the intialization that is never used here.
