[PATCH] arch/arm/Kconfig: enable ARM_MODULE_PLTS when LOCKDEP=y

[Anders Roxell]

While testing multi_v7_defconfig with LOCKDEP enabled, the kernel
fails to load simple modules, as reported by kselftest:

[   34.107620] test_printf: section 4 reloc 2 sym 'memset': relocation
28 out of range (0xbf046044 -> 0xc109f720)
selftests: printf.sh [FAIL]

The problem that is seen when LOCKDEP is enabled without
ARM_MODULE_PLTS, is that LOCKDEP eats so much memory that the top of the
kernel gets out of reach from the bottom of the module area.
