Except for very special cases (such as virtualization), the number of CPU

Therefore, use $(call force,CFG_TEE_CORE_NB_CORE,<value>) to set the

core/armv7: cleanup bootargs

In non-A-TF boot modes, OP-TEE core expects some boot arguments:
- nonsecure entry point, default expected from core register LR.
- pagestore address, when pager is enable, from core register R0.
- devicetree address, when DT is enable, from core register R2.

Some non-A-TF booted platform rely on u-boot has bootloader, and
expect u-boot to boot both linux and op-tee. armv7/linux expects the
following boot arguments:
- machine ID, expected from core register R1.
- devicetree address from core register R2.

Before this patch, some platform used CFG_TEE_GDB_BOOT together with
CFG_BUILT_IN_ARGS to both provide op-tee core boot arguments, and
relay linux argument from op-tee entry to linux kernel entry
(nonsecure entry).

This change proposes to rationalize a bit. Both linux and optee expect
device tree from register R2. op-tee could relay machine ID (R1).

This change removes CFG_TEE_GDB_BOOT and CFG_BUILT_IN_ARGS that are now
deprecated.

This change still supports CFG_PAGEABLE_ADDR, CFG_DT_ADDR and
CFG_NS_ENTRY_ADDR to statically define the pagestore, device tree
and nonsecure entry. These can be defined independently.

Since this change, if CFG_WITH_ARM_TRUSTED_FW is not enable, the
standard boot arguments (registers R1 and R2 at optee entry) are
propagated to the non secure entry.
