As per SLIMBus specs Value Elements and Information Elements
address map ranges from 0x000 - 0xFFF.

So allow register addresses up to 16 bits

Capability to attach an existing clk to a MMIO regmap was
introduced in 4.17rc1.

However, when using attached clk, regmap does not do the clk_get.
Therefore it should not do the clk_put when freeing the MMIO
regmap context.

There does not appear to be any users of attached clocks yet
so this would be a good time to make this change before anything
depends on the existing behaviour.

Currently when debugfs_create_dir() fails we receive a warning message
that provides no indication as to what was the directory entry that
failed to be created.

Improve the warning message by printing the directory name that failed
in order to help debugging.

When allocating dummy names we need to store a pointer to the string we
allocate so that we don't leak it on free.
