pinctrl: airoha: Fix AIROHA_PINCTRL_CONFS_DRIVE_E2 in an7583_pinctrl_match_data

Clang warns (or errors with CONFIG_WERROR=y / W=e):

pinctrl/mediatek/pinctrl-airoha.c:2064:41: error: variable 'an7583_pinctrl_drive_e2_conf' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
2064 | static const struct airoha_pinctrl_conf an7583_pinctrl_drive_e2_conf[] = {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Due to a typo, an7583_pinctrl_drive_e2_conf is only used within
ARRAY_SIZE() (hence no instance of -Wunused-variable), which is
evaluated at compile time, so it will not be needed in the final object
file.

Fix the .confs assignment for AIROHA_PINCTRL_CONFS_DRIVE_E2 in
an7583_pinctrl_match_data to clear up the warning.
