warp7: configs: bl33: Tidy up OPTEE defines

When booting in BL33 mode i.e. with u-boot loaded by OP-TEE we get the
following print-out.

Board: WARP7 in secure mode OPTEE DRAM 0xa0000000-0xa0000000

This is incorrect the right range is 0x9e000000-0xa0000000. This patch
fixes the defines on the warp7_bl33_defconfig file to tidy up the output.
