This improves performance by accessing NOR with the fine granularity that
the hardware permits, rather than the coarse granularity assumed by DiskIoDxe.

- Only read what needs reading, don't read the whole block.
- Don't write back buffers containing no data after an erase.
- Reduce number of NOR erases when writing data. Only erase the block
when required.

CFI Flash differentiates DeviceBaseAddress with BlockAddress in
its protocol. The DeviceBaseAddress was not considered in the
previous version of this driver.
This version also fixes some bugs in the implementation of the
CFI protocol.
This new version also uses the Boot Mode Hob to reinitialized the
FVB when Boot Mode is equal to BOOT_WITH_DEFAULT_SETTINGS.

This NOR Flash driver can be reused for other platform (eg: ARM Realview EB).
To make this driver reusable on other platforms the NorFlashPlatformLib library
has been created to abstract the platform specific bits such as the pre-requirements
steps to the initialization and the geometry of the NOR Flash regions.
