Add reserve memory for OP-TEE in U-Boot and in kernel device tree:
- no more reduce the DDR size in "memory" node:
CONFIG_SYS_MEM_TOP_HIDE is no more used
- U-Boot device-tree defines the needed "reserved-memory" for OP-TEE
and U-Boot should not use this reserved memory: board_get_usable_ram_top
use lmb lib to found the first free region, the not reserved
memory, enough to relocate U-Boot: the needed size of U-Boot
is estimated with gd->mon_len + CONFIG_SYS_MALLOC_LEN.
- the optee node ("optee@...": firmware with compatible "linaro,optee-tz")
and the associated "reserved-memory" are deactivated in kernel device
tree when OP-TEE is not detected by U-Boot to prevent kernel issue
(memory is reserved but not used, optee driver probe failed).
