The reported build error:
In function read_extcsd: mmc_cmds.c:72:18: error: MMC_BLOCK_MAJOR
undeclared (first use in this function)
In commit 118dc4a0909f ("mmc-utils: Remove unused MMC_BLOCK_MAJOR") the
define for MMC_BLOCK_MAJOR was dropped. In a way this commit is still
correct, but unfortunately it also introduced a dependency to a commit for
the Linux kernel (83fc5dd57f86 mmc: fix compilation of user API), which
fixes the mmc uapi header file (mmc: fix compilation of user API).
Rather than relying on the commit in the kernel, let's include the missing
header for MMC_BLOCK_MAJOR.
