Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * Bosch CC770 and Intel AN82527 CAN controllers on the ISA or PC-104 bus.
- * The I/O port or memory address and the IRQ number must be specified via
- * module parameters:
- *
- *   insmod cc770_isa.ko port=0x310,0x380 irq=7,11
- *
- * for ISA devices using I/O ports or:
- *
- *   insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11
- *
- * for memory mapped ISA devices.
- *
- * Indirect access via address and data port is supported as well:
- *
- *   insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11
- *
- * Furthermore, the following mode parameter can be defined:
- *
- *   clk: External oscillator clock frequency (default=16000000 [16 MHz])
- *   cir: CPU interface register (default=0x40 [DSC])
- *   bcr: Bus configuration register (default=0x40 [CBY])
- *   cor: Clockout register (default=0x00)
- *
- * Note: for clk, cir, bcr and cor, the first argument re-defines the
- * default for all other devices, e.g.:
- *
- *   insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000
- *
- * is equivalent to
- *
- *   insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000
