[PATCH] mptbase: use resource_size_t instead of unsigned long and u32

[Vitaly Bordug <vitb@kernel.crashing.org>]

From: Yuri Tikhonov <yur@emcraft.com>

    Use resource_size_t for pci_resource_start()/pci_resource_len()
    return values. This makes mptbase driver work correctly on 32
    bit systems with 64 bit resources (e.g. PPC440SPe).

    Do some minor cleanups in mpt_mapresources().
