stlink: Set speed before entering JTAG/SWD mode

Some boards require a slower clock speed because of passive components on the
JTAG/SWD lines. The previous implementation would first try to discover the
chips on the default speed, and only after discovery switch to the requested
adapter_khz speed.

This patch moves the speed change to just before entering the SWD/JTAG mode,
which should alleviate this problem.

Tested on an STLink V2 clone.

flash/stm32h7x: remove IWDG1_SW separate variable

Bit 4 in OPTSR is IWDG1_SW (the code originally called it IWDG1_HW, but
the reference manual refers to it as IWDG1_SW). This is broken out into

independent_watchdog_selection is not referenced anywhere else. Delete

The null pointer used as second parameter to gdb_put_packet() is
passed as second parameter to the memcpy() in line 408 of
gdb_put_packet_inner(). In this case memcpy() does not segfault
because also the parameter length is zero. Nevertheless, the
prototype of memcpy() requires a nonnull pointer.

Fixed by passing an empty string in place of the null pointer.

Issue highlighted by clang 7.0.0 with warning message:
"Null pointer passed as an argument to a 'nonnull' parameter"

src/jtag/drivers/ftdi: fix swd pin comment and links

- TDI/DO is not pin 2 and in fact, we don't even need to mention which
pin number it is. "TDI/DO pin" is descriptive enough.

- FT2232D link didn't work anymore. It could have been updated to the
current working FT2232D link but changed to link the FT2232H instead
which is the latest generation and the most commonly used these days.

- Taking advantage of the change, link to the MPSSE document updated.
It still worked but through a redirection, so updated just in case the
redirection stops working.

flash: stm32f2/f4/f7: Add One-Time-Porgrammable (OTP) support

The OTP is part of the flash memory. It has 512 (1024 for F7) bytes
and is organized in 16 sectors with 32 (64 for F7) bytes each.
The OTP is exposed as separate flash bank 1 and can be used
with the usual flash commands.

Writing the OTP can be done as follows:

> stm32f2x otp 1 enable
> flash write bank 1 foo.bin 0
> mdw 0x1fff7800 4
> verify_image foo.bin 0x1fff7800

from 2012 by Laurent Charpentier and he did most of the work.

Those jim commands that have incorrect mode were not detected nor
