This may cause side effects if disk does not support UDMA mode and also let bad performance.
The modification is to record supported mode and only try supported mode when do disk read/write.
Also this patch combines the code for read/readex/write/writex to reduce code size.

When Block I/O detects the media changed, block driver will reinstall block I/O protocol. If it happened during start() of partition driver, the reinstall protocol would results in the reentrant of the start(). In the patch, we check status of child detection to see whether need clean up the opened block I/O protocol in Start().
Besides, some checking of return status added in usbbus driver to improve robusticiy of the driver.

1)PciCommand.h: Add some macro constants definitions that will be used by other changes.
2)PciDeviceSupport.c:
a)Fix the bug that programs Non-Bridge Devices' Interrupt Line Register to 0x00. Although this register is rarely used in modern OS (actually, only Dos still uses it), it is good practice to modify it so it will align the spec. Please refer to PCI 3.0 Spec for the chapter on Interrupt line register.
b) Change the way used to detect VGA device. The old method will fail.
3)PciEnumeratorSupport.c: Make changes so Pci Driver will preserve those bits in Command & Bridge Control Register that were set by Customer's Chipset initialization code. Pci Driver is supposed to only touch those bits that are generic. Problems will arise if we destroy some initializations already done.
4)PciIo.c: PollIo() is not conformant to EFI spec so fix it. Also, some fixes are introduced to better support VGA card. These modifications are supposed to work with fixes in PciDeviceSupport.c.
5) PciOptionromSupport.c:Add the fix to enhance the logic working with OptionRom. Some legacy cards do not report correct imagelength so we add double check.
And add EFI_MIN and EFI_MAX macro definition since they are not currently defined in global files.
