mpc85xx: ws-ap3715i: enable access to u-boot env

Browse Source 
find_mtd_part() outputs /dev/mtdblockX, to which fw_setenv cannot
write, "/dev/mtd$(find_mtd_index '<vol name>')" could be used instead.

The envsize should also be changed to 0x1000 to make the CRC checksum
valid and the env block recognized by the uboot-envtools, but the
flash sector size remains 0x10000, otherwise the env block will be
readable but not writable.

The "read-only" mark within device tree is also removed.
