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().
