u-boot: Increase EFI variable buffer size
Debian's signed shim allocates too many EFI variables to fit in the EFI variable memory buffer. Normally it would then try to continue booting in non-secure-boot mode, but its error handling throws a synchronous abort that reboots the board, making it impossible to boot into Debian unless one manually loads GRUB instead of shim. Increase EFI variable buffer size to avoid triggering the bug. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
