[PATCH 1/2] Omap35xxPkg: add GetTimeInNanoSecond implementation

[Leif Lindholm]

Commit a63be426f8e3 ("ArmPlatformPkg: Store initial timer value") caused
BeagleBoard to stop building, due to Omap35xxTimerLib lacking an
implementation of GetTimeInNanoSecond (). So add one.

[PATCH 2/2] BeagleBoardPkg: add CapsuleLib resolution

[Leif Lindholm]

Commit 4bbcc285d5f7 ("ArmPkg/PlatformBootManagerLib: process pending
capsules") added a dependency on CapsuleLib. Add DxeCapsuleLibNull
resolution to BeagleBoardPkg.dsc to resolve this.
