[PATCH] pinctrl: stm32: Drop the nonexistent CONFIG_MACH_STM32MP25 from the STM32MP257 default

Commit 619f8ca4a73d ("pinctrl: stm32: add stm32mp257 pinctrl support")
made CONFIG_PINCTRL_STM32MP257 default to MACH_STM32MP25, following the
MACH_* pattern of the arm32 entries above it, but no Kconfig symbol of
that name exists and git log -S finds no Kconfig file that ever defined
one: the STM32MP25 family is arm64 only, where CONFIG_ARCH_STM32 covers
it. Commit dba0aff2b89b ("pinctrl: stm32: Allow compile as module for
stm32mp257") added "|| (ARCH_STM32 && ARM64)" next to it, so the first
half now evaluates to n and changes no configuration.

Drop the first half.
