Changes:

• Fixed a bug in AH24h_HSetBlocks.asm from r550. Trying to set a too large block size with an XT-CF card in DMA transfer mode would corrupt the stack.
• Fixed a bug from r545 where the list of devices under g_szDeviceTypeValues in Strings.asm was no longer up to date causing the boot menu to display the wrong string for devices numbered higher than DEVICE_8BIT_XTCF_PIO8.
• Made some fairly significant changes to the XT-CF code to reduce size. Two changes in functionality; 1) Added a simple check to validate the request for a change of the XT-CF transfer mode. 2) Changing transfer mode to use DMA no longer calls AH24h_SetBlockSize if the block size already is within the limits of DMA transfers. UNTESTED
• XTIDECFG now clears IDEVARS.bIRQ when changing IDE controller to a serial device to keep the boot menu from displaying it since the serial device doesn't use IRQs at all.
• Other minor optimizations.
