Add initial HSDK-4xD board support.
The ARC HS4x/HS4xD Development Kit includes a multicore ARC HS4xD-based
chip that integrates a wide range of interfaces including Ethernet,
HDMI, WiFi, Bluetooth, USB, SDIO, I2C, SPI, UART, I2S, ADC, PWM and
GPIO, as well as a Think Silicon GPU.

This patch add support of hsdk platform-specific commands:
hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq
environment variables/command line arguments
hsdk_clock get - save clock frequencies to axi_freq, cpu_freq
and tun_freq environment variables
hsdk_clock print - show CPU, AXI, DDR and TUNNEL current
clock frequencies.
hsdk_clock print_all - show all currently used clock frequencies.
hsdk_init - setup board HW in one of pre-defined configuration
(hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 /
hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4)
hsdk_go - run baremetal application on hsdk configured
by hsdk_init command.
This patch changes default behaviour of 'bootm' command:
now we are able to set number of CPUs to be kicked by setting
'core_mask' environment variable before 'bootm' command run.

ARC HS Development Kit board is a new low-cost
development platform sporting ARC HS38 in real silicon
with nice set of features such as:
* Quad-core ARC HS38 with 512 kB L2 cache and running @1GHz
* 4Gb of DDR (we use only lowest 1Gb out of it now)
* Lots of DesigWare peripherals
* Different connectivity modules:
- Synopsys HAPS HT3
- Arduino-compatible connector
- MikroBUS
This initial commit supports the following peripherals:
* UART (DW 8250)
* Ethernet (DW GMAC)
* SD/MMC (DW Mobile Storage)
* USB 1.1 & 2.0
