MFC r306219:

Update oce to version 11.0.50.0

Submitted by: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

The previous code makes a memory allocation in size of
struct mbx_common_read_write_flashrom plus 32KB and caps the actual
transfer size at 32KB. This is harmless as it is but may confuse
static code analyzer, so allocate a full 32KB instead.
