Rather than doing this in the IP code for the SDMA paging
engine, move it up to the core device level init level.
This should fix the scheduler init ordering.

v2: drop extra parens
v3: drop SDMA helpers
v4: Added a Fixes tag because amdgpu dereferences an uninitialized
    scheduler without this patch, and this patch fixes this. (Luben)

The GPU scheduler has now a variable number of run-queues, which are set up at
drm_sched_init() time. This way, each driver announces how many run-queues it
requires (supports) per each GPU scheduler it creates. Note, that run-queues
correspond to scheduler "priorities", thus if the number of run-queues is set
to 1 at drm_sched_init(), then that scheduler supports a single run-queue,
i.e. single "priority". If a driver further sets a single entity per
run-queue, then this creates a 1-to-1 correspondence between a scheduler and
a scheduled entity.

DRM_FORMAT_NV20 and DRM_FORMAT_NV30 formats is the 2x1 and non-subsampled
variant of NV15, a 10-bit 2-plane YUV format that has no padding between
components. Instead, luminance and chrominance samples are grouped into 4s
so that each group is packed into an integer number of bytes:

YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes

The '20' and '30' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a multiple
of 4.

Quite often during test corner cases IPC, JSM functions can flood
dmesg with warn or err messages. With that lost dmesg history.
Change warn, err to ratelimited versions in IPC, JSM to suppress
dmesg spam occurrence during fail test scenarios.

DRM_PANEL_ILITEK_ILI9882T is being split out from
DRM_PANEL_BOE_TV101WUM_NL6. Since the arm64 defconfig had the BOE
panel driver enabled, let's also enable the Ilitek driver.

At present, we have found that there may be a problem of blurred
screen during fast sleep/resume. The direct cause of the blurred
screen is that the IC does not receive 0x28/0x10. Because of the
particularity of the IC, before the panel enters sleep hid must
stop scanning, as i2c_hid_core_suspend before ili9882t_disable.
If move the ili9882t_enter_sleep_mode function to ili9882t_unprepare,
touch reset will pull low before panel entersleep, which does not meet
the timing requirements.. So in order to solve this problem, the IC
can handle it through the exception mechanism when it cannot receive
0x28/0x10 command. Handling exceptions requires a reset 50ms delay.
Refer to vendor detailed analysis [1].

Ilitek vendor also suggested switching the page before entering sleep to
avoid panel IC not receiving 0x28/0x10 command.

Note: 0x28 is display off, 0x10 is sleep in.

The Starry ILI9882t-based panel should never have been part of the boe
tv101wum driver, it is clearly based on the Ilitek ILI9882t display
controller and if you look at the custom command sequences for the
panel these clearly contain the signature Ilitek page switch (0xff)
commands. The hardware has nothing in common with the other panels
supported by this driver.

Break this out into a separate driver and config symbol instead.

If the placement here is out of convenience for using similar code,
we should consider creating a helper library instead.
