39d1fb94fa media: rockchip: vpss: prevent NULL dereference in rkvpss runtime resume 
- Validate vpss[i] and sw_base_addr before memset/memcpy operations
- Add bounds checking for dev_num to prevent array overflow
- Add error logging for invalid sw_base_addr during register restoration

This resolves kernel panic caused by accessing uninitialized sw_base_addr
during power management resume path. The issue occurred when restoring
VPSS hardware registers from suspend state.

ae4ced56fe media: rockchip: vpss: prevent NULL dereference in ofl_open 
Add NULL check for ofl->hw before accessing dev_lock mutex to avoid
kernel panic caused by translation fault at virtual address 0x27d8.

The crash occurs when opening V4L2 device if the hardware structure
 (ofl->hw) is not properly initialized. This adds defensive checks to:

    1. Validate ofl and ofl->hw pointers before mutex operations
    2. Return -ENODEV if hw structure is unavailable
    3. Prevent use-after-unlock in error paths

 Fixes system stability issues with v4l_id process (PID 229) when
 handling uninitialized hardware states. Detail issues can repo as below:

2ea7714258 phy: rockchip: inno-usb2: Add usb2 phy support for rv1126b 
RV1126B has one USB2.0 PHY with two ports, the OTG port
support OTG function and BC1.2, and the Host port only
support Host function. The SoC provides USB GRF to control
the internal UTMI+ interface and it also provides APB to
access the PHY internal registers for the USB HS/FS/LS
signal integrity tuning.

This patch adds the USB2.0 PHY tuning to improve the
signal integrity for RV1126B.

1. Enable pre-emphasis during non-chirp phase.
2. Set HS eye height to 425mv(default is 400mv).
3. Set Rx squelch trigger point configure to 112.5mv.
