On newer Tegra releases, early boot SID override programming and SID
override programming during resume is handled by bootloader.
In the function tegra186_mc_program_sid() which is getting removed, SID
override register of all clients is written without checking if secure
firmware has allowed write on it or not. If write is disabled by secure
firmware then it can lead to errors coming from secure firmware and hang
in kernel boot.
Also, SID override is programmed on-demand during probe_finalize() call
of IOMMU which is done in tegra186_mc_client_sid_override() in this same
file. This function does it correctly by checking if write is permitted
on SID override register. It also checks if SID override register is
already written with correct value and skips re-writing it in that case.

The TIM IP on the RZ/V2M comes with 32 channels, but the ISP has
full control of channels 0 to 7, and channels 24 to 31. Therefore
Linux is only allowed to use channels 8 to 23.

Since kernel 5.3.4 my laptop (ICH8M controller) does not see Kingston
SV300S37A60G SSD disk connected into a SATA connector on wake from
suspend. The problem was introduced in c312ef1763 ("libata/ahci: Drop
PCS quirk for Denverton and beyond"): the quirk is not applied on wake
from suspend as it originally was.
It is worth to mention the commit contained another bug: the quirk is
not applied at all to controllers which require it. The fix commit
09d6ac8dc5 ("libata/ahci: Fix PCS quirk application") landed in 5.3.8.
So testing my patch anywhere between commits c312ef1763 and
09d6ac8dc5 is pointless.
Not all disks trigger the problem. For example nothing bad happens with
Western Digital WD5000LPCX HDD.
Test hardware:
- Acer 5920G with ICH8M SATA controller
- sda: some SATA HDD connnected into the DVD drive IDE port with a
SATA-IDE caddy. It is a boot disk
- sdb: Kingston SV300S37A60G SSD connected into the only SATA port
Sample "dmesg --notime | grep -E '^(sd |ata)'" output on wake:

Commit c312ef1763 dropped ahci_pci_reset_controller() which internally
calls ahci_reset_controller() and applies the PCS quirk if needed after
that. It was called each time a reset was required instead of just
ahci_reset_controller(). This patch puts the function back in place.

Add pinctrl definitions for Rockchip RV1126.
From RK3568 on-wards pinctrl configurations are maintained
in common conf file rockchip-pinconf.dtsi and it is available
in arm64 path (arch/arm64/boot/dts/rockchip/rockchip-pinconf.dtsi).
So, include the same conf file to RV1126 pinctrl from arm64 path.
