Samsung DTS ARM changes for v4.19
1. Add two new S5Pv210 boards: Samsung Galaxy S and Samsung Galaxy S 4G
mobile phones. Both are from family codenamed Aries. The Samsung
Galaxy S was released on the market in 2010 with Android operating
system. At that time, it was the Samsung's flagship model.
This brings support for storage (SD card and internal memory), PMIC,
RTC, fuel-gauge, keys, USB (in peripherial mode) and WiFi.
2. Add missing secondary CPU properties.
3. Cleanup from old files and properties.

Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which
requires register range "ccb-mii" <0x18003000 0x1000>. This range
overlaps with MDIO cmd and param registers (<0x18003000 0x8>).
Essentially, the platform driver partly acts like a MDIO bus driver,
hence to use of this register range.
In some Northstar devices like Linksys EA9500, secondary switch is
connected via external MDIO. The only way to access and configure the
external switch is via MDIO bus. When we enable the MDIO bus in it's
current state, the MDIO bus and any child buses fail to register because
of the register range overlap.
On Northstar, the USB 3.0 PHY is connected at address 0x10 on the
internal MDIO bus. This change moves the usb3_phy node and makes it a
child node of internal MDIO bus.
Thanks to Rafał Miłecki's commit af850e14a7 ("phy: bcm-ns-usb3: add
MDIO driver using proper bus layer") the same USB 3.0 platform driver
can now act as USB 3.0 PHY MDIO driver.

On all versions of Tegra30 Cardhu, the reset signal to the NXP PCA9546
I2C mux is connected to the Tegra GPIO BB0. Currently, this pin on the
Tegra is not configured as a GPIO but as a special-function IO (SFIO)
that is multiplexing the pin to an I2S controller. On exiting system
suspend, I2C commands sent to the PCA9546 are failing because there is
no ACK. Although it is not possible to see exactly what is happening
to the reset during suspend, by ensuring it is configured as a GPIO
and driven high, to de-assert the reset, the failures are no longer
seen.
Please note that this GPIO is also used to drive the reset signal
going to the camera connector on the board. However, given that there
is no camera support currently for Cardhu, this should not have any
impact.
