Pali Rohár 1dcbcc715e arm: mvebu: Replace hardcoded values 0x0030/0x4030 by proper calculation
These hardcoded values were calculated from CONFIG_SPL_TEXT_BASE macro. Now
this macro is configurable via Kconfig, so calculate values 0x0030/0x4030
at compile time via CONFIG_SPL_TEXT_BASE option. Values 0x0030/0x4030
represents offset of CONFIG_SPL_TEXT_BASE from address 0x40000000.
