This function used to be for adding a list of requests to be actioned on
relocation. Revert it back to this purpose, to avoid problems with boards
which need control of their MTRRs (i.e. those which don't use FSP).
The mtrr_set_next_var() function is available when the next free
variable-MTRR must be set, so this can be used instead.

At present this leaves the stack at the pre-relocation value. This is not
ideal since we want to have U-Boot running entirely from the top of
memory.
In addition, the new global_data pointer is not actually used, since
the global_data pointer itself is relocated, then the pre-relocation value
is changed, so the effective value (after relocation) does not update.
Adjust the implementation to follow the 32-bit code more closely, with a
trampoline function which is passed the new stack and global_data pointer.
This ensures that the correct values come through even when relocating.

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

clear it relates to the stub. Move both up to just under the choice that
