Silicon/SynQuacer: load I2C driver before platform DXE driver
To ensure that the I2C master protocol is installed immediately onto
the handles created by PlatformDxe in its entry point, force the
SynQuacerI2cDxe driver to be loaded before PlatformDxe. These handles
are recursively connected by the DXE core as soon as they appear, and
so ensuring that the I2C master protocol driver is available at this
time will ensure that these handles will be connected to it right away.
This is useful when implementations of architectural protocols such as
RTC or the EFI variable store, which should become available long before
the ordinary dispatch of UEFI driver model drivers is started at the end
of DXE, are based on I2C.
