[U-Boot] [PATCH 04/11] vexpress64: Kconfig: add CONFIG_SYS_BOOTM_LEN

[Ryan Harkin]

vexpress64 kernels are usually over 8 MBytes in length, so setting the
max uImage length to 0x4000000 (64 Mbytes) should give us plenty of
scope for expansion.

I mostly chose this length to match other board configs that use
"(64 << 20)", however, Kconfig doesn't allow arithmetic operations.
