CONFIG_EXPERT exposes too many config options that do not matter for
development. E.g. it prohibits using the default values for the various
SH_SCI options. However, CONFIG_EMBEDDED selects CONFIG_EXPERT, so it
cannot be disabled.
Hence disable CONFIG_EMBEDDED, and compensate for the loss of
CONFIG_DEBUG_KERNEL by enabling the latter.
Actual impact, all harmless:
- CONFIG_NAMESPACES=y (plus a few related CONFIG_*_NS options),
- CONFIG_SYSCTL_SYSCALL=n,
- CONFIG_SERIAL_SH_SCI_NR_UARTS changed from 20 to 18,
- Some HID support became enabled,
- CONFIG_DEBUG_MEMORY_INIT=y,
Refresh the result.
