pinctrl: tegra238: remove unused entries

The -Wunused-const-variable check points out a number of added
entries that are currently not referenced:

drivers/pinctrl/tegra/pinctrl-tegra238.c:1169:27: error: 'soc_gpio86_phh3_pins' defined but not used [-Werror=unused-const-variable=]
 1169 | static const unsigned int soc_gpio86_phh3_pins[] = {
      |                           ^~~~~~~~~~~~~~~~~~~~
drivers/pinctrl/tegra/pinctrl-tegra238.c:1165:27: error: 'uart5_cts_phh2_pins' defined but not used [-Werror=unused-const-variable=]
 1165 | static const unsigned int uart5_cts_phh2_pins[] = {
      |                           ^~~~~~~~~~~~~~~~~~~
drivers/pinctrl/tegra/pinctrl-tegra238.c:1161:27: error: 'uart5_rts_phh1_pins' defined but not used [-Werror=unused-const-variable=]
 1161 | static const unsigned int uart5_rts_phh1_pins[] = {
      |                           ^~~~~~~~~~~~~~~~~~~

Remove them for now, they can just be added back if they get
used in the future.
