uniphier: make uniphier_mmap_setup() work with PIE
BL2_BASE, BL31_BASE, and BL32_BASE are defined in platform_def.h,
that is, determined at link-time.
On the other hand, BL2_END, BL31_END, and BL32_END are derived from
the symbols produced by the linker scripts. So, they are fixed-up
at run-time if ENABLE_PIE is enabled.
To make it work in a position-indepenent manner, use BL_CODE_BASE and
BL_END, both of which are relocatable.
