i386 boot: replace boot_ioremap with enhanced bt_ioremap - enhance bt_ioremap
This patch makes it possible for bt_ioremap() to be used before paging_init(), via providing an early implementation of set_fixmap() that can be used before paging_init(). This way boot_ioremap() can be replaced by bt_ioremap().
