We already have MAX() defined, add MIN() to the common helpers header.
Using the common helper also fixes a bug in tpmdrivers's MIN() where
it was reverted.

Changes:
v2:
* updated the comment about a fixed bug
Implement elf_get_file_size to determine the size of an ELF image
that has been loaded into a buffer much larger than the actual size
of the original file. We determine the size by searching for the
farthest offset declared by the ELF headers.

This patch adds TPM 2.0 support along with the firmware API that Linux
uses to transfer the firmware log.
The firmware API follows the "PFW Virtual TPM Driver" specification.
The API has callers in existing Linux code (prom_init.c) from TPM 1.2
times but the API also works for TPM 2.0 without modifications.
The TPM 2.0 support logs PCR extensions of measurements of code and data.
For this part we follow the TCG specification "TCG PC Client
Platform Firmware Profile Specification" (section "Event Logging").
Other relevant specs for the construction of TPM commands are:
- Trusted Platform Module Library; Part 2 Structures
- Trusted Platform Module Library; Part 3 Commands

According to TFTP Booting extension, after the success of BOOTP, BOOTREPLY
packet should be copied to bootp-response property under "/chosen"
While in current case, even when DHCP was used, bootp-response was being set. So
set bootp-response when BOOTP is used and dhcp-response for DHCP

The code in lib/libnet/netload.c uses write_mm_log() to write
error messages to the management module log, thus we need to
provide this function in Paflof, too, when we want to link
the netload code to Paflof later.

Every caller of SLOF_alloc_mem_aligned() assumes the size is the first
argument while it is not.
This switches align and size and fixes random memory corruptions.
This is grep for SLOF_alloc_mem_aligned with this patch applied:
include/helpers.h|27| extern void *SLOF_alloc_mem_aligned(long size, long align);
lib/libveth/veth.c|103| buffer_list = SLOF_alloc_mem_aligned(8192, 4096);

Current code only works with 512 bytes read.
Moreover, Qemu ignores the guest set features request. In the set
features request SLOF indicates to qemu that it is not support
VIRTIO_BLK_F_BLK_SIZE feature. Code in qemu suggests that virtio-blk
is not implementing set_guest_feature.
