I2c driver will now enumerate all devices from the PCD table without
assumption that this table ends with '\0' entry. This condition occurred
to be toolchain-dependent. Size of table will be gathered from PCD's size.

MvEeprom driver produces MARVELL_EEPROM_PROTOCOL, which can be used by
other drivers or applications. Working EFI_I2C_IO_PROTOCOL is required
by driver to operate.
EEPROM devices' addresses need to be fed via 'PcdEepromI2cAddresses'.

MvI2cDxe driver was adapted to generic UEFI I2C stack. Connection with
following interfaces was required:
- EFI_I2C_MASTER_PROTOCOL
- EFI_I2C_BUS_CONFIGURATION_MANAGEMENT_PROTOCOL
- EFI_I2C_ENUMERATE_PROTOCOL
Driver exports configuration options via PCDs. Configurable options
include:
- PcdI2cSlaveAddresses - should contain a list of valid I2C devices'
addresses on bus
- PcdI2cBaseAddresses - physical address of I2C controller registers
- PcdI2cClockFrequency - I2c clock frequency on platform
Drivers of devices on I2C bus should never use EFI_I2C_MASTER_PROTOCOL
directly. Instead, these ought to utilise EFI_I2C_IO_PROTOCOL produced
by generic UEFI stack.
