This serie add support for the analog and digital filter binding
for the stm32f7 i2c driver.
An additional patch add also debug informations, displayed in case
of errors.

The digital filter related computation are present in the driver
however the programming of the filter within the IP is missing.
The maximum value for the DNF is wrong and should be 15 instead of 16.

In addition to the pkey check for user pages, advertise pkr_mask also to
cache the conditions where protection key checks for supervisor pages
are needed. Add CR4_PKS in mmu_role_bits to track the pkr_mask update on
a per-mmu basis.
In original cache conditions of pkr_mask, U/S bit in page tables

Replace kmap_atomic_pfn() with kmap_local_pfn() which is preemptible and
can take page faults.
Remove the indirection of the dump page and the related cruft which is not
