[PATCH RESEND v3 0/2] media: i2c: Add Samsung S5KJN5 image sensor

[Wenmeng Liu <wenmeng.liu@oss.qualcomm.com>]

This series adds support for the Samsung S5KJN5, a 50 MP 10-bit RAW MIPI
CSI-2 image sensor.

This is implemented as a separate driver rather than extending the existing
s5kjn1 driver. Although both sensors belong to the same family, they are
different parts with different register maps and power supplies.
Combining support for both devices in a single driver would result in very
little shared code while introducing separate initialization and control
paths, so keeping them as independent drivers is cleaner.

Power Supplies:
| Power Rail | S5KJN5 | S5KJN1 |
|------------|--------|--------|
| VDDD       | 1.0 V  | 1.0 V  |
| VDDA       | 2.2 V  | 2.8 V  |
| VDDIO      | 1.8 V  | 1.8 V  |
| VDDIO1p2   | 1.2 V  | -      |
| VDDM       | 1.0 V  | -      |

Tested on the Qualcomm Hawi qrd board.

Changes in v3:
- Add vddm-supply to the regulator list.
- Drop GBRG from Kconfig, file header and MODULE_DESCRIPTION. -- Vladimir
- Compute pixel_rate at runtime from the link frequency instead of
  storing it in the mode. -- Vladimir
- Split the init sequence into two tables around the 5 ms delay and
  drop the .delay_us field/handling. -- Vladimir
- Remove unused v4l2_ctrl pointers and the unused <media/v4l2-device.h>.
  -- Vladimir
- Move all control flag setting to the end of s5kjn5_init_controls(). -- Vladimir
- Fix s_ctrl() to apply controls when CONFIG_PM is disabled
  (pm_runtime_get_if_active() returns -EINVAL).
- Use S5KJN5_CHIP_ID in the init sequence; reword the clock-rate error;
  minor style fixes (reverse x-mas tree, ret init).

Changes in v2:
- dt-bindings: drop the "T:" MAINTAINERS entry -- Krzysztof
- Rename vdda2 -> vddio1p2; fix supply descriptions (vddio = 1.8 V VDD18,
  vddio1p2 = 1.2 V VDDIO12) -- Wenmeng
