firmware: Drop FIRMWARE_IN_KERNEL Kconfig option

It doesn't actually do anything.  Merge its help text into
EXTRA_FIRMWARE.

Fixes: 5620a0d1aa ("firmware: delete in-kernel firmware")
Fixes: 0946b2fb38 ("firmware: cleanup FIRMWARE_IN_KERNEL message")

Enabling this option will build each required firmware blob
specified by EXTRA_FIRMWARE into the kernel directly, where
request_firmware() will find them without having to call out to
userspace. This may be useful if your root file system requires a
device that uses such firmware and you do not wish to use an
initrd.
This single option controls the inclusion of firmware for
every driver that uses request_firmware(), which avoids a
proliferation of 'Include firmware for xxx device' options.
Say 'N' and let firmware be loaded from userspace.
