Restore original (pre r315760) naming for Tegra SDHCI device.
Newbus handles multiple equally named device classes without problems,

In contrast, the driver module name must be unique, so "<foo>_shdci"

Define StrCmp in a funky was to be bug-compatible with EDK2 code.
Paper over a coverity issue:
*** CID 1372592: API usage errors (BAD_COMPARE)
/lib/libefivar/efivar-dp-parse.c: 2723 in DevPathFromTextiSCSI()
Truncating the result of "strcmp" to "unsigned short" may cause it
to be misinterpreted as 0. Note that "strcmp" may return an integer
besides -1, 0, or 1.
We do this by making StrCmp return either 0 or 1 for equal or
not-equal. There's a bug in the DevPathFromTextiSCSI cast of the
return value and this workaround will fix it without breaking other
users of StrCmp (all of which test for == 0).

Add a flag BI_BRAND_ONLY_STATIC to specify that the brand only
matches static binaries.
Interpretation of the 'static' there is that the binary must not
specify an interpreter. In particular, shared objects are matched by
the brand if BI_CAN_EXEC_DYN is also set.
This improves precision of the brand matching, which should eliminate
surprises due to brand ordering.
