In pursuit of the eventual goal of removing cbfs_boot_locate() (and
direct rdev access) from CBFS APIs, this patch replaces all remaining
"simple" uses of the function call that can easily be replaced by the
newer APIs (like cbfs_load() or cbfs_map()). Some cases of
cbfs_boot_locate() remain that will be more complicated to solve.

Since prog_locate() was eliminated, prog_rdev() only ever represents the
loaded program in memory now. Using the rdev API for this is unnecessary
if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to
translate back to that if necessary.

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.

Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for
both the traditional and ULT variants of Broadwell, because the CPU
driver for Haswell already contains CPUIDs for both Broadwell types.
Without this patch, Broadwell CPUs would hang when trying to print the
first console log message, but only if flashconsole was not enabled.
This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell
CPUIDs and microcode) and went unnoticed until now because the tests
were done with flashconsole enabled, which somehow boots properly even
though the console time tracking would not work (depends on TSC).
Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.
