[PATCH 1/2] pci: layerscape: Fix the disabling of Expansion ROM BAR

[Z.q. Hou]

From: Hou Zhiqiang <Zhiqiang.Hou at nxp.com>

The software will still get non-zero Expansion ROM BAR size
even when the BAR_EN bit is cleared. The BAR_EN bit of
register EXP_ROM_BAR_MASK_RC is not working as expected,
so this patch changes to mask all the bits to make it.

Fixes: 80afc63fc342 ("pci: layerscape: add pci driver based on DM")
