configs: stm32mp15: Update x_ADDR_R defines to allow bigger kernel size usage

In case kernel is compiled with kernel debug configuration
(memory, network, scheduler, oops, spinlocks debugging ....)
kernel binary size can be up to 60-70% bigger.

Some U-Boot variables need to be updated to allow usage of bigger
kernel image.
