Fix JUNO AArch32 build

This patch fixes the inconsistency with regards as to how
BL2_BASE/BL2U_BASE and BL2_LIMIT/BL2U_LIMIT macros are defined
when building Juno to run in AArch32 mode at EL3. In this case,
BL32 is compiled for AArch32 whereas BL1 and BL2 are compiled
for AArch64. This resulted in BL32 conditionally compiling a
different definition of the above mentioned macros from BL1/BL2.
This is fixed by taking into consideration the
JUNO_AARCH32_EL3_RUNTIME build flag as well in the conditional
compilation check.
