efi/tpm: Pass correct address to memblock_reserve

[ Upstream commit f4cd18c5b2000df0c382f6530eeca9141ea41faf ]

memblock_reserve() expects a physical address, but the address being
passed for the TPM final events log is what was returned from
early_memremap(). This results in something like the following:

[    0.000000] memblock_reserve: [0xffffffffff2c0000-0xffffffffff2c00e4] efi_tpm_eventlog_init+0x324/0x370

Pass the address from efi like what is done for the TPM events log.
