CAMERA_PWR_EN controls two different power supplies that cameras will use.
The hardware killswitch controls a third one. Describe that appropriately.
The pinctrl that describes the gpio that is used in 2 places here is added
to the pmic. This is done because pmic is powered early enough to make
sure this will work.
When we would have put the same pinctrl property into the 2 regulator nodes
(instead of the pmic), we'd get:
imx8mq-pinctrl 30330000.pinctrl: pin MX8MQ_IOMUXC_GPIO1_IO00 already requested by regulator-csi-1v8; cannot claim for regulator-vcam-2v8

- Workaround a limitation in SiFive PLIC interrupt chip which
silently ignores an EOI when the interrupt line is masked.
- Provide the missing mask/unmask implementation for the CSKY MP
interrupt controller.
PCI/MSI:
- Prevent a use after free when PCI/MSI interrupts are released by
destroying the sysfs entries before freeing the memory which is
accessed in the sysfs show() function.
- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse
the chip comes out of reset with all MSI entries masked, which due
to the missing masking capability never get unmasked.
- Move the check which prevents accessing the MSI[X] masking for XEN
back into the low level accessors. The recent consolidation missed
that these accessors can be invoked from places which do not have
that check which broke XEN. Move them back to he original place
instead of sprinkling tons of these checks all over the code"
