Support for more than 8bpc was added recently in the driver but it defaults to the maximum supported bpc - locking out these modes. This should be a user configurable option such that the user can select what bpc configuration they would like. [How] This patch adds support for getting and setting the amdgpu driver specific "max bpc" property on the connector. It also adds support for limiting the output bpc based on the property value. The default limitation is the lowest value in the range, 8bpc. This was the old value before the range was uncapped. This patch should be updated/replaced later once common drm support for max bpc lands.

Due to this during hotplug, when PLL sharing conditions are checked for new display phy_pix_clk variable will be 0 and for displays that are already enabled phy_pix_clk will have some value. Hence PLL will not be shared and if the display hardware doesn't have any more PLL to assign, mode set will fail due to resource unavailability.

Issue with this is that some of the GT workarounds live in the MMIO space which gets lost during engine resets. So far the registers in 0x2xxx and 0xbxxx address range have been identified to be affected. This losing of applied workarounds has obvious negative effects and can even lead to hard system hangs (see the linked Bugzilla). Rather than just restoring this re-application, because we have also observed that it is not safe to just re-write all GT workarounds after engine resets (GPU might be live and weird hardware states can happen), we introduce a new class of per-engine workarounds and move only the affected GT workarounds over. Using the framework introduced in the previous patch, we therefore after engine reset, re-apply only the workarounds living in the affected MMIO address ranges. v2: * Move Wa_1406609255:icl to engine workarounds as well. * Rename API. (Chris Wilson) * Drop redundant IS_KABYLAKE. (Chris Wilson) * Re-order engine wa/ init so latest platforms are first.

This is a temporary implementation which later in the series gets fused with the existing per context workaround list handling. It is separated at this stage since the following patch fixes a bug which needs to be as easy to backport as possible. Also, since in the following patch we will be adding a new class of workarounds (per engine) which can be applied from interrupt context, we straight away make the provision for safe read-modify-write cycle. v2: * Change dev_priv to i915 along the init path.
