treewide: drop CONFIG_EMBEDDED

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched
to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

mips: update config files

Clean up config files by:
- removing configs that were deleted in the past
- removing configs not in tree and without recently pending patches
- adding new configs that are replacements for old configs in the file

For some detailed information, see Link.

MIPS: configs: Cleanup old Kconfig options

CONFIG_MTD_NAND_IDS is gone and not needed (part of CONFIG_MTD_NAND)
since commit f16bd7ca0457 ("mtd: nand: Kill the MTD_NAND_IDS Kconfig
option").

CONFIG_IOSCHED_DEADLINE, CONFIG_IOSCHED_CFQ and CONFIG_DEFAULT_NOOP are
gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers").

The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be
now enabled by default (along with MQ_IOSCHED_KYBER).

The BFQ_GROUP_IOSCHED is the only multiqueue scheduler which comes with
group scheduling so select it in configs previously choosing
CFQ_GROUP_IOSCHED.

MIPS: configs: Remove useless UEVENT_HELPER_PATH

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

MIPS: Regenerate defconfigs

A couple of patches have come up recently to remove particular instances
of obsolete Kconfig symbols from defconfigs. Rather than doing this
piecemeal, simply regenerate them all.

MIPS: defconfigs: add MTD_SPI_NOR (new dependency for M25P80)

These defconfigs contain the CONFIG_M25P80 symbol, which is now
dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to satisfy
the new dependency.

At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.
