armv8: fsl-layerscape: Add support of QorIQ LS1012A SoC
The QorIQ LS1012A processor, optimized for battery-backed or
USB-powered, integrates a single ARM Cortex-A53 core with a hardware
packet forwarding engine and high-speed interfaces to deliver
line-rate networking performance.
This patch add support of LS1012A SoC along with
- Update platform & DDR clock read logic as per SVR
- Define MMDC controller register set.
- Update LUT base address for PCIe
- Avoid L3 platform cache compilation
- Update USB address, errata
- SerDes table
- Added CSU IDs for SDHC2, SAI-1 to SAI-4

+LS1012A
+--------
+The LS1012A features an advanced 64-bit ARM v8 Cortex-
+A53 processor, with 32 KB of parity protected L1-I cache,
+32 KB of ECC protected L1-D cache, as well as 256 KB of
+ECC protected L2 cache.
+
+The LS1012A SoC includes the following function and features:
+ - One 64-bit ARM v8 Cortex-A53 core with the following capabilities:
+ - ARM v8 cryptography extensions
+ - One 16-bit DDR3L SDRAM memory controller, Up to 1.0 GT/s, Supports
+ 16-/8-bit operation (no ECC support)
+ - ARM core-link CCI-400 cache coherent interconnect
+ - Packet Forwarding Engine (PFE)
+ - Cryptography acceleration (SEC)
+ - Ethernet interfaces supported by PFE:
+ - One Configurable x3 SerDes:
+ Two Serdes PLLs supported for usage by any SerDes data lane
+ Support for up to 6 GBaud operation
+ - High-speed peripheral interfaces:
+ - One PCI Express Gen2 controller, supporting x1 operation
+ - One serial ATA (SATA Gen 3.0) controller
+ - One USB 3.0/2.0 controller with integrated PHY
+ - One USB 2.0 controller with ULPI interface. .
+ - Additional peripheral interfaces:
+ - One quad serial peripheral interface (QuadSPI) controller
+ - One serial peripheral interface (SPI) controller
+ - Two enhanced secure digital host controllers
+ - Two I2C controllers
+ - One 16550 compliant DUART (two UART interfaces)
+ - Two general purpose IOs (GPIO)
+ - Two FlexTimers
+ - Five synchronous audio interfaces (SAI)
+ - Pre-boot loader (PBL) provides pre-boot initialization and RCW loading
+ - Single-source clocking solution enabling generation of core, platform,
+ DDR, SerDes, and USB clocks from a single external crystal and internal
+ crystaloscillator
+ - Thermal monitor unit (TMU) with +/- 3C accuracy
+ - Two WatchDog timers
+ - ARM generic timer
+ - QorIQ platform's trust architecture 2.1
