Subject: [PATCH v2] arm: footbridge: Netwinder: Add KConfig select CLKEVT_I8253 to fix build failure

This patch fixes a build failure for the netwinder_defconfig by adding
the necessary select CLKEVT_I8253 statement to the KCONFIG option.

Without this patch the build fails with this linker error:
isa-rtc.c:(.init.text+0x11d4): undefined reference to
`clockevent_i8253_init'
isa-rtc.c:(.init.text+0x11dc): undefined reference to `i8253_clockevent'
arch/arm/mach-footbridge/built-in.o:(.data+0x18c): undefined reference
to `i8253_clockevent'

This is because the functions are guarded by a #ifdef
CONFIG_CLKEVT_I8253

KernelVersion: Linux-next 20110812
but this is also present in Linus' current tree since July 1st.
(since commit e6220bd "i8253: Create common clockevent implementation")

v2:
Added the option in the right alphabetical order.
I also adjusted the alphabetical order for ARCH_CATS so both are
similar
