Subject: [PATCH] ARM: davinci: always select CONFIG_CPU_ARM926T

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

The select was lost by accident during the multiplatform conversion.
Any davinci-only

arm-linux-gnueabi-ld: arch/arm/mach-davinci/sleep.o: in function `CACHE_FLUSH':
(.text+0x168): undefined reference to `arm926_flush_kern_cache_all'

Fixes: f962396ce292 ("ARM: davinci: support multiplatform build for ARM v5")
Signed-off-by: Arnd Bergmann <arnd@...db.de>

I ran into this today for the first time after five years of randconfig testing
with the bug in place, so it is clearly very hard to hit.

It's an obvious fix, so I'm applying it to the soc/arm branch directly
for this week's pull requests.
