[PATCH] ARM: integrator: remove unused variable

[Arnd Bergmann]

The patch to add the new generic config space accessors removed
a useless spinlock, but left the flags variable in place, which
now causes a build warning:

arch/arm/mach-integrator/pci_v3.c: In function 'pci_v3_preinit':
arch/arm/mach-integrator/pci_v3.c:614:16: warning: unused variable 'flags' [-Wunused-variable]

This removes it.
