regsub doesn't work correctly on macOS Catalina, which results in
an incorrect CHIPNAME derived from the current target. Since regsub
is only used by this target, replace it with a simple string search
for '.' followed by a substring. This is funcionally equivalent to
what the regular expression was doing, but instead relies in simpler
string operations that should have little to no differences
between systems.
Also, refactor CHIPNAME detection into proc stm32h7x_chipname, so
it's always retrieved in the same way without duplicating the code.

Prerequisites:
The users of OpenOCD as well as computer programs interacting with OpenOCD are expecting that certain commands
do the same thing across all the targets.
Rules to follow when writing scripts:
1. The configuration script should be defined such as , for example, the following sequences are working:
reset
flash info <bank>
and
reset
flash erase_address <start> <len>
and
reset init
load
In most cases this can be accomplished by specifying the default startup mode as reset_init (target command
in the configuration file).
2. If the target is correctly configured, flash must be writable without any other helper commands. It is
assumed that all write-protect mechanisms should be disabled.
3. The configuration scripts should be defined such as the binary that was written to flash verifies
(turn off remapping, checksums, etc...)
flash write_image [file] <parameters>
verify_image [file] <parameters>
4. adapter speed sets the maximum speed (or alternatively RCLK). If invoked
multiple times only the last setting is used.
interface/xxx.cfg files are always executed *before* target/xxx.cfg
files, so any adapter speed in interface/xxx.cfg will be overridden by
target/xxx.cfg. adapter speed in interface/xxx.cfg would then, effectively,
set the default JTAG speed.
Note that a target/xxx.cfg file can invoke another target/yyy.cfg file,
so one can create target subtype configurations where e.g. only
amount of DRAM, oscillator speeds differ and having a single
config file for the default/common settings.
