Lenovo ThinkPad X60: Init CBMEM early for CBMEM console support.
Enable `EARLY_CBMEM_INIT` for CBMEM console support by looking how
other boards do this.
This commit is tested by enabling the CBMEM console (`CONSOLE_CBMEM` in
Kconfig) and then in GRUB 2 (as a payload) with the cbmemc command from
the cbmemc module and in userspace with ./cbmem -c. Both worked.
