Plus various fixes from jk: - Fix compile warnings. We have a bunch of unused functions. - Remove unused members of struct bt_host - Fix whitespace issues - Use explicit u8 type for bt registers to avoid any issues with signed vs unsigned types. - Remove chrdev_region, use module_platform_driver - Unify device name to bt-host - Use a more explicit compatible string. The interface we're using here is specific to the aspeed hardware implementation. - Use a dynamic miscdev; no need to use a global miscdev here. - Avoid global bt_host. Rather than having a global bt_host, use references from the file & miscdev. This removes the restriction on the number of bt-host devices. - Add ioctl to assert SMS_ATN - Remove bt_host->ctrl, nothing uses it. - Read bt ctrl state after poll_wait - Fix unit address for ibt - Add facility for interrupt-driven BT messages. This change adds a facility for the bt-host driver to use interrupts rather than polling via a timer. If we find an interrupts property in the device tree, we'll enable interrupts on the bt device. - Use devm_ioremap_resource(). No need to unpack struct resource, and we don't need ioremap_uncached here.

The driver allows configuring the current-limiting resistor for the charger, as well as the voltage to apply to the coincell (or capacitor) when charging.

Specifically it adds the cxl callbacks that are called from the core powerpc mm code which must always exist irrespective of if the cxl module is loaded or not. This is similar to how cell works with CONFIG_SPU_BASE. This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if the cxl module is loaded and in use, returning immediately if it is not. If it is in use it calls into the cxl SLB invalidation code.
