Do not set CONFIG_LSM_MMAP_MIN_ADDR; use the default.
This is the address limit for checking SELinux mmap_zero permission, which predated the CAP_SYS_RAWIO check and intentionally uses a fixed limit rather than /proc/sys/vm/mmap_min_addr to avoid being mutable by userspace.
When we first enabled this in our kernels, we were conservative and only set it to 4096. However, since Android sets /proc/sys/vm/mmap_min_addr to 32768, we should just use the default value (also 32768 for ARM, 65536 for others) specified by security/Kconfig. Remove the explicit setting of the value from the defconfig file.
