mflash: Remove this broken flash driver

This is causing repeated build failures. Its design is so fundamentally
broken that if someone actually wants to use it, a full rewrite is the
only option. So it's not even worth deprecating in the hope that someone
will notice and fix it, just get rid of it.

@subsection mFlash Configuration
@cindex mFlash Configuration

@deffn {Config Command} {mflash bank} soc base RST_pin target
Configures a mflash for @var{soc} host bank at
address @var{base}.
The pin number format depends on the host GPIO naming convention.
Currently, the mflash driver supports s3c2440 and pxa270.

Example for s3c2440 mflash where @var{RST pin} is GPIO B1:

@example
mflash bank $_FLASHNAME s3c2440 0x10000000 1b 0
@end example

Example for pxa270 mflash where @var{RST pin} is GPIO 43:

@example
mflash bank $_FLASHNAME pxa270 0x08000000 43 0
@end example
@end deffn

@subsection mFlash commands
@cindex mFlash commands

@deffn Command {mflash config pll} frequency
Configure mflash PLL.
The @var{frequency} is the mflash input frequency, in Hz.
Issuing this command will erase mflash's whole internal nand and write new pll.
After this command, mflash needs power-on-reset for normal operation.
If pll was newly configured, storage and boot(optional) info also need to be update.
@end deffn

@deffn Command {mflash config boot}
Configure bootable option.
If bootable option is set, mflash offer the first 8 sectors
(4kB) for boot.
@end deffn

@deffn Command {mflash config storage}
Configure storage information.
For the normal storage operation, this information must be
written.
@end deffn

@deffn Command {mflash dump} num filename offset size
Dump @var{size} bytes, starting at @var{offset} bytes from the
beginning of the bank @var{num}, to the file named @var{filename}.
@end deffn

@deffn Command {mflash probe}
Probe mflash.
@end deffn

@deffn Command {mflash write} num filename offset
Write the binary file @var{filename} to mflash bank @var{num}, starting at
@var{offset} bytes from the beginning of the bank.
