When running the EFI app, we need to exit boot services before jumping
to Linux.
At some point it may be possible to jump to Linux and pass on the system
table, and:
* install the device-tree as configuration table
* use LoadImage() to load the kernel image (e.g. from memory)
* start the image with StartImage()
This should allow the Linux efistub to be used. For now, this is not
implemented.

Add the missing code to handle this. For a 64-bit kernel the entry
address is 0x200 bytes after the normal entry.
Rename the parameter to boot_linux_kernel() accordingly. Update the
comments to indicate that these are addresses, not pointers.

The current vesa structure only provides a 32-bit value for the frame
buffer. Many modern machines use an address outside the range.
It is still useful to have this common struct, but add a separate
frame-buffer address as well.
Add a comment for vesa_setup_video_priv() while we are here.

This function calls rtc_write32, which has a different signature
depending on if (SPL_)DM_RTC is enabled or not. This could result in a
mismatch in SPL if DM_RTC was enabled but SPL_DM_RTC, as the non-DM
declaration would still be used in SPL even though the implementation
would be for non-DM_RTC. We are switching to the correct definitions in
the next commit, so this will become a compilation error. Since
fsp_save_s3_stack is not called from SPL, avoid compiling it if
(SPL_)DM_RTC is disabled.

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.
Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.
