Redefine binding for regulator-coupled-max-spread property in a way that
max-spread values are defined per regulator couple instead of defining
single max-spread for the whole group of coupled regulators.
With that change the following regulators coupling configuration will be
possible:

Device tree binding was changed in a way that now max-spread values must
be defied per regulator pair. Limit number of pairs in order to adapt to
the new binding without changing regulators code.

This change makes it so that we use the same approach that was already in

In snd_hdac_bus_init_chip(), we enable interrupt before
snd_hdac_bus_init_cmd_io() initializing dma buffers. If irq has
been acquired and irq handler uses the dma buffer, kernel may crash
when interrupt comes in.
Fix
This patch implements sparsemem support for risc-v which helps pave the
way for memory hotplug and eventually P2P support.
We introduce Kconfig options for virtual and physical address bits which
are used to calculate the size of the vmemmap and set the
MAX_PHYSMEM_BITS.
