Tomas Vanek 5a2608bbbc flash Kinetis: handle all types of watchdog, disable in reset-init
Active watchdog forces reset during armv7m_checksum_memory()
in verify_image command if run just after reset init.

COP watchdog in KL series and WDOG32 in KE1 series
have longer timeout however they need to be disabled too.

The change extends 'kinetis disable_wdog' command to optionally
probe the chip and use appropriate algorithm to disable watchdog.

Setting of cache type is also split from flash_support flags.

Tcl command 'kinetis disable_wdog' is called in reset-init event.

Tomas Vanek c4d4c32a50 flash Kinetis: implement automatic bank creation based on device probe
Kinetis flash driver services huge number of MCU types. They have
one, two or four flash banks with option of FlexNVM. It would
require ~36 config files just for Kx series, more for KLx, KVx and KE1x.

The change implements alternative approach:
- configuration file creates just one pflash bank (common for all devices)
- when a device is probed, additional pflash or flexnvm banks are created
based on flash layout of the connected MCU
- created banks have names with optional numbering e.g. kx.pflash0 kx.pflash1
kx.flexnvm0 kx.flexnvm1
- the first bank gets renamed if numbering is used

Automatic bank creation is enabled by tcl command 'kinetis create_banks'.

Used solution has a drawback: other banks than pflash0 are not accessible
until pflash0 is probed. Fortunately gdb attach and standard programming
accesses banks in right sequence.

Tomas Vanek 6d5b4d709c flash Kinetis: Detect RESET/WDOG loop, fix detection of secured MCU
Kinetis driver checks MDM STAT register to detect secured state of MCU.
Original version often reported a blank device as secured one.
Change #3010 has not fixed all false reports.
After changes in arm_adi_v5 infrastructure secured devices was not detected
at all.

New algorithm uses multiple MDM STAT reads and counts MDM_STAT_SYSSEC and
MDM_STAT_FREADY bits. Both secured MCU and MCU locked-up in RESET/WDOG loop
are detected reliably.

Detection is run in both kx.cfg and klx.cfg from examine-start event,
not examine-end as before. Event is configured only for non hla adapter.

Minor fix in klx.cfg: commented out adapter_khz 24000 in reset-init.
Such frequency is not supported in VLPR CPU mode and with JTAG.

Andreas Fritiofson 10331d2007 cfg: Fix Kinetis kwikstik/kx config
The flash definition belongs in the target cfg. Add some working area
and suitable reset_config.

Make kx.cfg more similar to klx.cfg.

Disable rclk as it is dead slow and a fixed 1MHz clock seems to work.
