intelspi: Add support for ddb/kdb -compatible polled mode

2023-08-03T16:10:50Z

Required for Apple and Microsoft -compatible HID-over-SPI drivers. Most logic was already implemented in commit 3c0867343819 "spibus: extend API: add cs_delay ivar, KEEP_CS and NO_SLEEP flags". It dissallowed driver sleeps in the interrupt context. This commit extends this feature to handle ddb/kdb context with following: - Skip driver locking if SPI functions were called from kdb/ddb. - Reinitialize controller if kdb/ddb initiated SPI transfer has interrupted another already running one. Does not work very reliable yet. Reviewed by: manu Differential Revision: https://reviews.freebsd.org/D41247

Also adds fixups and cleanups: - apply the child's mode/speed - implement suspend/resume support - use RF_SHAREABLE interrupts - use bus_delayed_attach_children since the transfer can use interrupts - add support for newly added spibus features (cs_delay and flags) Operation tested on Broadwell (Wildcat Point) MacBookPro12,1. Attachment also tested on Kaby Lake (Sunrise Point) Pixelbook. Reviewed by: wulf MFC after: 1 month Differential revision: https://reviews.freebsd.org/D29249
