OvmfPkg: QemuFlashFvbServicesRuntimeDxe: rewrap source code to 79 chars
Some of the line lengths in this driver are atrocious. While we have to
put up with the status quo outside of OvmfPkg, we can at least rewrap this
driver before refactoring it.
In the FvbInitialize() function there's no way around introducing two
local variables, just for the sake of sensibly rewrapping the code.
Furthermore, in "FwBlockService.c" the function comment blocks are now
indented; their original position causes diff to print bogus function
names at the top of hunks.

-Arguments:
- This - Calling context
- Lba - Block in which to begin Read
- Offset - Offset in the block at which to begin Read
- NumBytes - On input, indicates the requested write size. On
- output, indicates the actual number of bytes Read
- Buffer - Buffer containing source data for the Read.
-
-Returns:
- EFI_SUCCESS - The firmware volume was read successfully and
- contents are in Buffer
- EFI_BAD_BUFFER_SIZE - Read attempted across a LBA boundary. On output,
- NumBytes contains the total number of bytes returned
- in Buffer
- EFI_ACCESS_DENIED - The firmware volume is in the ReadDisabled state
- EFI_DEVICE_ERROR - The block device is not functioning correctly and
- could not be read
- EFI_INVALID_PARAMETER - NumBytes or Buffer are NULL
+ Routine Description:
+
+ Reads data beginning at Lba:Offset from FV. The Read terminates either
+ when *NumBytes of data have been read, or when a block boundary is
+ reached. *NumBytes is updated to reflect the actual number of bytes
+ written. The write opertion does not include erase. This routine will
+ attempt to write only the specified bytes. If the writes do not stick,
+ it will return an error.
