arm: dra76: Add support for ES1.0 detection

Browse source 
dra76 family is a high-performance, infotainment application
device, based on OMAP architecture on a 28-nm technology.
This contains most of the subsystems, peripherals that are
available on dra74, dra72 family. This SoC mainly features
Subsystems:
- 2 x Cortex-A15 with max speed of 1.8GHz
- 2 X DSP
- 2 X Cortex-M4 IPU
- ISS
- CAL
- DSS
- VPE
- VIP
Connectivity peripherals:
- 1 USB3.0 and 3 USB2.0 subsystems
- 1 x SATA
- 2 x PCI Express Gen2
- 3-port Gigabit ethernet switch
- 2 x CAN
- MCAN

Adding CPU detection support for the dra76 ES1.0 soc
and update prcm, control module, dplls data.
