Subject: [RFC PATCH 05/18] ARM: msm: fix qsd8x50 rev.a support
The MSM_SMI_BASE variable was accidentally declared inside
of an #ifdef, which makes it depend on a Kconfig symbol,
and incompatible between multiple machines that may
coexist in the kernel.
This fixes the problem by duplicating the qsd8x50_io_desc
for the two revisions.
