* src/bus/pxa2x0.c (set_data_in, setup_data): Added new 'adr' parameter. Used real data bus width
		for data reading (based on patch 792591, thanks to Guennadi Liakhovetski).
	All function callers updated.
	(pxa250_bus_read_next, pxa250_bus_read_end): Used real data bus width for data reading (based on
		patch 792591, thanks to Guennadi Liakhovetski).
	* src/bus/sa1110.c (set_data_in, setup_data, sa1110_bus_read_next, sa1110_bus_read_end): Ditto.
	* src/bus/sh7727.c (set_data_in, setup_data, sh7727_bus_read_next, sh7727_bus_read_end): Ditto.

* Added additional checks for valid ByteBlaster cable connection and enabled all variants
of the cable (patch 793313, Rojhalat Ibrahim).
* Used real data bus width for data reading in PXA2x0, SA1110, and SH7727 bus drivers
(based on patch 792591, thanks to Guennadi Liakhovetski).
* Added BOOT_DEF register emulation for PXA2x0 bus driver.
* Fixed minor bugs.
