bcma: move bus struct setup into early part of host specific code
This change is important for SoC host. In future we will want to know chip ID (needed for early MIPS boot) before doing cores scanning. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Acked-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
