Convert CONFIG_SYS_BOOTM_LEN to Kconfig
This converts the following to Kconfig:
CONFIG_SYS_BOOTM_LEN
As part of this, rework error handling in boot/bootm.c so that we pass
the buffer size to handle_decomp_error as CONFIG_SYS_BOOTM_LEN will not
be available to host tools but we do know the size that we passed to
malloc().
