fs/ext2: rename BR2_TARGET_ROOTFS_EXT2_BLOCKS to BR2_TARGET_ROOTFS_EXT2_SIZE

Browse Source 
This change deprecates the ext2/3/4 rootfs size in blocks symbol in
favor of one that mimic the fs-size argument behavior of mkfs (i.e.
size in a human readable format accepting k, m, g or t suffix or their
upper-case variants).

This change also updates the defconfigs that used to set
BR2_TARGET_ROOTFS_EXT2_BLOCKS symbol.

Specify the file system size as a number of 1024-byte blocks.
The size of the filesystem image. If it does not have a suffix,
it is interpreted as power-of-two kilobytes. If it is suffixed
by 'k', 'm', 'g', 't' (either upper-case or lower-case), then
it is interpreted in power-of-two kilobytes, megabytes,
gigabytes, terabytes, etc.
