UPSTREAM: rockchip: move CONFIG_ENV_SIZE and CONFIG_ENV_OFFSET to Kconfig

This commit adds ENV_SIZE and ENV_OFFSET configuration items for
ARCH_ROCKCHIP, but keeps these non-visible (i.e. not prompt is given).
With these new items present, the configuration from the header files
is moved to Kconfig.

Keeping these non-visible is necessary to have the possibility to
select new default values if CONFIG_IS_IN_* is changed (interactively
or with oldconfig). Otherwise it will always be set to a previous
value if used with a prompt. As an example if we do a defconfig with
CONFIG_IS_IN_MMC and change it to CONFIG_IS_IN_SPI_FLASH via
menuconfig, ENV_SIZE and ENV_OFFSET will not be changed to the correct
values as defconfig will already have set them to the default values
of CONFIG_IS_IN_MMC in .config.

env: Convert CONFIG_ENV_IS_IN... to a choice

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since
it is the default.
