When u-boot runs in S-mode, the M-mode runtime firmware
(BBL or equivalent) uses memory range in 0x80000000 to
0x80200000. Due to this, we cannot use 0x80000000 as
SYS_TEXT_BASE when running in S-mode. Instead for S-mode,
we use 0x80200000 as SYS_TEXT_BASE.
Even Linux RISC-V kernel ignores/reserves memory range
0x80000000 to 0x80200000 because it runs in S-mode.
