common: Drop floppy disk support
This seems pretty old now. It has not been converted to driver model and is not used by any boards. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>

If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
forced to a value that ensures that CCSR is not relocated.
-- Floppy Disk Support:
- CONFIG_SYS_FDC_DRIVE_NUMBER
-
- the default drive number (default value 0)
-
- CONFIG_SYS_ISA_IO_STRIDE
-
- defines the spacing between FDC chipset registers
- (default value 1)
-
- CONFIG_SYS_ISA_IO_OFFSET
-
- defines the offset of register from address. It
- depends on which part of the data bus is connected to
- the FDC chipset. (default value 0)
-
- If CONFIG_SYS_ISA_IO_STRIDE CONFIG_SYS_ISA_IO_OFFSET and
- CONFIG_SYS_FDC_DRIVE_NUMBER are undefined, they take their
- default value.

- if CONFIG_SYS_FDC_HW_INIT is defined, then the function
- fdc_hw_init() is called at the beginning of the FDC
- setup. fdc_hw_init() must be provided by the board
- source code. It is used to make hardware-dependent
- initializations.

- CONFIG_IDE_AHB:
Most IDE controllers were designed to be connected with PCI
interface. Only few of them were designed for AHB interface.
