Correct the preprocessor directive used to check for 64-bit kernel
support in the `zboot_go` function. The code previously checked for
`CONFIG_X86_RUN_64BIT`, which is not the correct configuration option
for determining if the kernel should run in 64-bit mode. The correct
option is `CONFIG_X86_64`.

Rather than holding the state in the implementation code, move it to the

This structure is supposed to handle any type of booting
programmatically, i.e. without needing a command to be executed. Move
the x86-specific members into it and use it instead of
struct zboot_state. Provide a macro so access is possible without adding
lots of #ifdefs to the code.
This will allow the struct to be used for all four types of booting
(bootm, bootz, booti and zboot).
Call bootm_init() to init the state, to match other boot methods.
Note that some rationalisation could be performed on this. But this
is tricky since addresses are stored as strings in several places. Also
some strings combine multiple arguments into one. So to keep this task
somewhat manageable, we content ourselves with just getting everything
into the same struct

With the updated changes to bootargs substitution[1], the zboot command
needs to be updated to get its command line from an environment variable
instead of a memory address. This is because the command-line string must
be updated to convert %U to ${uuid}, etc.
In any case it is more flexible to use a environment variable and it is
best to do this before the release to avoid a subsequent change.
Update the command accordingly.
