arm: bootm: fix sp detection at end of address range
This fixes 'arch_lmb_reserve()' for ARM that tries to detect in which
DRAM bank 'sp' is in.
This code failed if a bank was at the end of physical address range
(i.e. size + length overflowed to 0).
To fix this, calculate 'bank_end' as 'size + length - 1' so that such
banks end at 0xffffffff, not 0.
Fixes: 15751403b6 ("ARM: bootm: don't assume sp is in DRAM bank 0")
