For some targets (like nrf51) sysfs driver is too slow. This
patch implements memory maped driver for IMX processors.
Mostly based on bcm2835gpio. Tested on imx6ul CPU. However, it should
work on any NXP IMX CPU.

Micromips is 16bit oriented, branch and jumps are
16 bit based. The upper half 16bits of a 32bit instruction
with the major opcode, must go first in the instruction
stream, hence the SWAP16 macro and swap16 array function,
needed if the code is written as 32 bit word in little endian
cores. Endianess info added to ejtag_iinfo. Pointer to
ejtag_info and isa field added to pracc context.
MIPS32 code are renamed to MIPS32_ISA_...
To select the isa, the new code has an additional isa parameter
(1 for micromips, 0 for mips32).
In JR instruction the isa bit must be set to execute
micromips code.
The suffix u is added to the OP codes to avoid signed/unsigned
comparison errors and to make sure the right shift is
performed logically.
The isa in debug mode is updated in the poll function.
Code for miniprograms, in kernel mode, need to be converted.

Basing on:
STM32L0x1 RM0377
STM32L0x2 RM0376
STM32L0x3 RM0367
STM32Lxxxx RM0038

correct values for memory layouts were selected:
id = 0x447 STM32L0xx (Cat.5) <- dual bank flash
for size 192 or 128 KBytes, single bank for 64 KBytes
id = 0x436 STM32L1xx (Cat.4 / Cat.3 - Medium + /
High Density) <- only one size of the bank,
default values are correct
id = 0x437 STM32L1xx (Cat.5 / Cat.6) <- always dual bank,
but size of the bank can be different

For that reason .part_info field in struct stm32lx_flash_bank
is a dynamic field with fields copied from stm32lx_parts[]

for specific chips and memory sizes.
