arm_adi_v5: drop ANY_ID from table dap_part_nums

The initial version of the table dap_part_nums contains only the
part number of the device and not the manufacturer ID.
This causes collisions between devices with same part number but
from different manufacturer.
The table has been extended to include the manufacturer JEDEC code
in commit 2f131d3c3004 ("ARM ADIv5: CoreSight ROM decode part
number and designer id").
For two old/legacy table's entries reported without manufacturer
code it was defined a special ANY_ID manufacturer, meaning skip
the check for manufacturer!
The two legacy entries report the comment "from OMAP3 memmap", and
thanks to the associated string has been possible through Google
to identify a Master Report [1] about using OpenOCD with the OMAP3
in a BeagleBoard. The ROM table is printed with OpenOCD command
"dap info 1" at page 8 and reports the Peripheral ID required to
extract the manufacturer ID that, out of any surprise, belong to
Texas Instruments.

Set the two missing manufacturer ID to Texas Instruments JEDEC
code.

Remove the now redundant definition and use of ANY_ID.

While revisiting this old code, remove also the useless comment
"0x113: what?". It was introduced in commit ddade10d4a93 ("ARM
ADIv5: "dap info" gets more readable") and from the same dump in
[1] it's clearly another element in OMAP3. It is listed as entry
0x8 in the ROM table and there is no further info available.
OpenOCD will anyway list it as:
Designer is 0x017, Texas Instruments
Part is 0x113, Unrecognized
Another link https://elinux.org/BeagleBoardOpenOCD reports the
text "Part number 0x113: This is ????", which sounds familiar!
No public document from Texas Instruments reports what is this
device at address 0x54012000.
