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

independent_watchdog_selection is not referenced anywhere else. Delete

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.

gdb_server: remove warning for stepi after gdb_sync

The command "gdb_sync" is used to resynchronize gdb with OpenOCD.
It is supposed to be follow by the gdb command "stepi" that will
be ignored by OpenOCD.

Don't annoy the user with a warning message when the stepi
command is ignored, but simply log a debug message.

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
> stm32f2x otp 1 disable

Note: This patch is largely a rebase/cleanup of a patch
from 2012 by Laurent Charpentier and he did most of the work.

No new Clang-Analyzer warnings.
