This patch fixes a regression introduced by commit b810253.
It substitutes the type __u8 to u8 in the uapi header cxl.h,
because the latter is not always defined in userland build
environments, in particular when cross-compiling libcxl on
x86_64 linux machines (RHEL6.7 and Ubuntu 16.04).
This patch also changes the size of the field data_size, and
makes it constant, to support 32-bit userland applications
running on big-endian ppc64 kernels transparently.
This breaks the (young) API that has been merged in v4.8.

Changes since v1:
Added an explanation for the proposed API change in the log.
Note:
As far as I know, cxlflash is the only known user of the API.
Yes, ideally, we'd like to change the type of 'data_size' to something
smaller/constant and were expecting it's still doable since the API was
merged to 4.8 and the expected user (cxlflash) hasn't started using the
API yet.
