[U-Boot] [PATCH v9 10/10] 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 0x, not
