flashrom: bump flashrom to upstream 1.3 and fix flash.sh progress_bar

[tlaurion]

Based on commit JonathonHall-Purism@2bb58f7

• Extended to not have the progress bar stuck at 99%. Progress bar drawing under Heads still needed until properly implemented upstream see https://ticket.coreboot.org/issues/390
• Removes flashrom DUMMY and AST1100 on both x86 and ppc64.
  • AST1100 can be added through board config option instead of bloating smaller SPI boards ROMs.

TODO: probably split flashrom into flashrom-stable/flashrom-upstream/flashrom-dasharo and have boards use the one needed. I suspect flashrom-stable will be even smaller.

---

Good news is that #1422 #1381 and this PR merged under #1398 can be compiled for legacy boards, dodging #1421 issue for the moment.

[tlaurion]

Testing request under #1398.

Now that master has sizes.txt and console output of sizes of built binaries etc, rebasing on master and addressing @JonathonHall-Purism comment #1398 (comment)

[tlaurion]

Ok time for comparisons!!!!

Master last commit includes sizes.txt report. We will use t520-hotp-maximized sizes output step to compare cost of PR addition here. The raw output is available here. which we will use with diff to see what changed.

Some analysis

• flashrom being a binary is stripped and then packed under tools.cpio to fainlly be packed under initrd.cpio.xz, which is explained by the data above:
