The driver only uses the registers up to offset 0x54. Since the EFUSE
registers are in the middle of the NEMC registers, we only request
the registers we will use for now - that way the EFUSE driver can
probe too.

Add new API k3_ringacc_request_rings_pair() to request pair of rings at
once, as in the most cases Rings are used with DMA channels, which need to
request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and
one to receive completions (RX/TX CQ). This will allow to simplify Ringacc
API users.

Merge tag 'memory-controller-drv-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/drivers

Memory controller drivers for v5.9

The drivers/memory directory with memory controller drivers, over the
last days grew in numbers but lacked any coordinated care.  The generic
part (device tree helpers) were pulled in through various trees,
depending on driver needs.

The patchset is a first try to improve code quality of memory controller
drivers.  Mostly these are non-intrusive fixes for GCC, checkpatch or
sparse warnings.  This also fixes missing SPDX tags or improves generic
code quality (whitespace, const correctness).

Last commit appoints also Krzysztof Kozlowski as a maintainer.
