Tegra: rename secure scratch register macros

This patch renames all the secure scratch registers to reflect their
usage.

This is a list of all the macros being renamed:

- SECURE_SCRATCH_RSV1_* -> SCRATCH_RESET_VECTOR_*
- SECURE_SCRATCH_RSV6 -> SCRATCH_SECURE_BOOTP_FCFG
- SECURE_SCRATCH_RSV11_* -> SCRATCH_SMMU_TABLE_ADDR_*
- SECURE_SCRATCH_RSV53_* -> SCRATCH_BOOT_PARAMS_ADDR_*
- SECURE_SCRATCH_RSV55_* -> SCRATCH_TZDRAM_ADDR_*

NOTE: Future SoCs will have to define these macros to
      keep the drivers functioning.
