Add infrastructure to handle regulator undervoltage events for MMC/eMMC
cards. When an undervoltage is detected, the new handler performs a
controlled emergency suspend using a short power-off notification,
skipping the cache flush to maximize the chance of a safe shutdown.
After the operation, the card is marked as removed to prevent further
I/O and possible data corruption.
This is implemented by introducing MMC_POWEROFF_UNDERVOLTAGE to the
mmc_poweroff_type enum and refactoring the suspend logic into an
internal __mmc_suspend() helper that allows the caller to skip the cache
flush if required. The undervoltage handler is registered as a bus
operation and invoked from the core undervoltage path.
If power-off notification is not supported by the card, the handler
falls back to sleep or deselecting the card.
Additionally, update the shutdown path to avoid redundant shutdown
steps if the card is already removed

Implement the core infrastructure to allow MMC bus types to handle
REGULATOR_EVENT_UNDER_VOLTAGE events from power regulators. This is
primarily aimed at allowing devices like eMMC to perform an emergency
shutdown to prevent data corruption when a power failure is imminent.
This patch introduces:
- A new 'handle_undervoltage' function pointer to 'struct mmc_bus_ops'.
Bus drivers (e.g., for eMMC) can implement this to define their
emergency procedures.
- A workqueue ('uv_work') in 'struct mmc_supply' to handle the event
asynchronously in a high-priority context.
- A new function 'mmc_handle_undervoltage()' which is called from the
workqueue. It stops the host queue to prevent races with card removal,
checks for the bus op, and invokes the handler.
- Functions to register and unregister the regulator notifier, intended
to be called by bus drivers like 'mmc_attach_mmc' when a compatible
card is detected.
The notifier is only registered for the main vmmc supply, as
undervoltage handling for vqmmc or vqmmc2 is not required at this
time.

we can safely omit the size argument and let strscpy() infer it using
