cbfs: Pull handling of the CBFS_CACHE mem_pool into CBFS core
This patch pulls control of the memory pool serving allocations from the CBFS_CACHE memlayout area into cbfs.c and makes it a core part of the CBFS API. Previously, platforms would independently instantiate this as part of boot_device_ro() (mostly through cbfs_spi.c). The new cbfs_cache pool is exported as a global so these platforms can still use it to directly back rdev_mmap() on their boot device, but the cbfs_cache can now also use it to directly make allocations itself. This is used to allow transparent decompression support in cbfs_map().
