Subject: [PATCH v2 3/5] davinci: fix sleep.S build error on ARMv4

From: Arnd Bergmann <arnd@...db.de>

When building a multiplatform kernel that includes armv4 support,
the default target CPU does not support the blx instruction,
which leads to a build failure:

arch/arm/mach-davinci/sleep.S: Assembler messages:
arch/arm/mach-davinci/sleep.S:56: Error: selected processor does
not support `blx ip' in ARM mode

Add a .arch statement in the sources to make this file build.
