Simon Glass c1c3fe2307 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.

[trini: Move all of the imply logic to default X if Y so it works again]

Some MIPS boards can be configured for either little or big endian
byte order. These modes require different U-Boot images. In general there
is one preferred byteorder for a particular system but some systems are
just as commonly used in the one or the other endianness.

Enable this to include exception vectors in the U-Boot image. This is
required if the U-Boot entry point is equal to the address of the
CPU reset exception vector (e.g. U-Boot as ROM loader in Qemu,
U-Boot booted from parallel NOR flash).
Disable this, if the U-Boot image is booted from DRAM (e.g. by SPL).
In that case the image size will be reduced by 0x500 bytes.

Select this if the initial stack frame could be setup in SRAM.
Normally the initial stack frame is set up in DRAM which is often
only available after lowlevel_init. With this option the initial
stack frame and the early C environment is set up before
lowlevel_init. Thus lowlevel_init does not need to be implemented
in assembler.

Select this (or let it be auto-selected by not defining any cache
sizes) in order to allow U-Boot to automatically detect the sizes
of caches at runtime. This has a small cost in code size & runtime

time it would be beneficial to configure it.
