The HPCP bit is set by bioses for on-board sata ports either because they think sata is hotplug capable in general or to allow Windows to display a "device eject" icon on ports which are routed to an external connector bracket. However in Redhat Bugzilla #1310682, users report that with kernel 4.4, where this bit test first appeared, a lot of partitions on sata drives are now mounted automatically. This patch should fix redhat and a lot of other distros which unconditionally automount all devices which have the "removable" bit set.

Currently, workaround for broken WD drives is applied always, slowing down all drives. And it has a bug - it's not applied after resume. Apply the workaround only if the error really appears (SErr == 0x1000500). This allows unaffected drives to run at full speed (provided that no affected drive is connected to the controller). Also make sure the workaround is re-applied on resume. Tested on VT6421. As SCR registers access is known to cause problems on VT6420 (and I don't have it to test), keep the workaround applied always on VT6420.

This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes).

Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary.
