Subject: [PATCH] TPM: Fix compiler warnings
Stop defining our own Event type in tpm.c instead use the one from
the header, so that it matches the function prototype.
Note this requires some further code changes to go from all lowercaps
of the private Event type to the CamelCaps from the header.
Also cast buf, which gets passed as a efi_physicall_address_t to an
integer, to avoid the compiler complaining about passing a pointer as
an integer.
