arm64: dts: exynos: Add initial device tree support for Exynos7885 SoC

Add initial Exynos7885 device tree nodes with dts for the Samsung Galaxy
A8 (2018), a.k.a. "jackpotlte", with model number "SM-A530F".
Currently this includes some clock support, UART support, and I2C nodes.

arm64: dts: exynos: use dedicated wake-up pinctrl compatible in Exynos850

Older Samsung Exynos SoC pin controller nodes (Exynos3250, Exynos4,
Exynos5, Exynos5433) with external wake-up interrupts, expected to have
one interrupt for multiplexing these wake-up interrupts. Also they
expected to have exactly one pin controller capable of external wake-up
interrupts.

It seems however that newer ARMv8 Exynos SoC like Exynos850 and
ExynosAutov9 have differences:
1. No multiplexed external wake-up interrupt, only direct,
2. More than one pin controller capable of external wake-up interrupts.

Use dedicated Exynos850 compatible for its external wake-up interrupts
controller to indicate the differences.

arm64: dts: exynos: drop incorrectly placed wakeup interrupts in Exynos850

The pin controller device node is expected to have one (optional)
interrupt. Its pin banks capable of external interrupts, should define
interrupts for each pin, unless a muxed interrupt is used.

Exynos850 defined the second part - interrupt for each pin in wake-up
pin controller - but also added these interrupts in main device node,
which is not correct.

ARM: exynos: only do SMC_CMD_CPU1BOOT call on Exynos4

On Exynos5 the call is simply ignored by most variants of the
trustzone firmware.  However, on some devices it instead causes the
device to hang, so let's avoid the call for the SoCs where it should
not be needed.

To see that the call is ignored, we can look into sboot/tzsw.  On most
of the Exynos{4,5} devices the part of sboot/tzsw that seem to handle
the secure monitor calls is quite easy to recognise, the SMC number is
compared to known ones, and if equal it branches to the relevant
function.  In assembly this looks something like:

;-- handle_smc:
0x00000514      650070e3       cmn r0, 0x65
0x00000518      0a00000a       beq loc.smc_cmd_reg
0x0000051c      010070e3       cmn r0, 1
0x00000520      6c00000a       beq loc.smc_cmd_init
0x00000524      020070e3       cmn r0, 2
0x00000528      6b00000a       beq loc.smc_cmd_info
0x0000052c      030070e3       cmn r0, 3
0x00000530      6e00000a       beq loc.smc_cmd_sleep
0x00000534      060070e3       cmn r0, 6
0x00000538      ae00000a       beq loc.smc_cmd_save_state
0x0000053c      070070e3       cmn r0, 7
0x00000540      b400000a       beq loc.smc_cmd_standby
0x00000544      2b01001a       bne loc.smc_return_minus1

where above example is from exynos5420-arndale-octa.  As can be seen
the case where r0 is 4 (i.e. SMC_CMD_CPU1BOOT) is not handled.  The
annotations are taken from github.com/hsnaves/exynos5410-firmware,
where a large part of the exynos5410 trustzone firmware has been
reverse-engineered.

arm64: dts: exynos: use dedicated wake-up pinctrl compatible in ExynosAutov9

Older Samsung Exynos SoC pin controller nodes (Exynos3250, Exynos4,
Exynos5, Exynos5433) with external wake-up interrupts, expected to have
one interrupt for multiplexing these wake-up interrupts. Also they
expected to have exactly one pin controller capable of external wake-up
interrupts.

It seems however that newer ARMv8 Exynos SoC like Exynos850 and
ExynosAutov9 have differences:
1. No multiplexed external wake-up interrupt, only direct,
2. More than one pin controller capable of external wake-up interrupts.

Use dedicated ExynosAutov9 compatible for its external wake-up interrupts
controller to indicate the differences.
