Subject: [PATCH 2/4] pinctrl: renesas: rzg2l: Adjust bit masks for PIN_CFG_VARIABLE to use BIT(62)

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Shift the bit masks for `PIN_CFG_PIN_MAP_MASK` and `PIN_CFG_PIN_REG_MASK`,
to accommodate `PIN_CFG_VARIABLE` using `BIT(62)`.

Previously, these bit masks were placed higher up in the bit range, which
did not leave room for `PIN_CFG_VARIABLE` at `BIT(62)`. By adjusting these
masks, we ensure that `PIN_CFG_VARIABLE` can occupy `BIT(62)` without any
conflicts. The updated masks are now:
- `PIN_CFG_PIN_MAP_MASK`: `GENMASK_ULL(61, 54)` (was `GENMASK_ULL(62, 55)`)
- `PIN_CFG_PIN_REG_MASK`: `GENMASK_ULL(53, 46)` (was `GENMASK_ULL(54, 47)`)
