bus: ixp4xx: fix IXP4XX_EXP_T1_MASK
commit 6722e46513e0af8e2fff4698f7cb78bc50a9f13f upstream.
The IXP4XX_EXP_T1_MASK was shifted one bit to the right, overlapping
IXP4XX_EXP_T2_MASK and leaving bit 29 unused. The offset being wrong is
also confirmed at least by the datasheet of IXP45X/46X [1].
Fix this by aligning it to IXP4XX_EXP_T1_SHIFT.
