The documentation for misc_read() says:
Return: number of bytes read if OK (may be 0 if EOF), -ve on error
The Rockchip efuse driver implements this so it should return the number
of bytes read rather than zero on success. Fix this so that the driver
follows the usual contract for read operations.

Refactor the driver to use driver data and ops to simplify handling

Use readl_poll_sleep_timeout instead of a custom poll loop, and add
validation of input parameter to main read op.

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Newer Rockchip socs like the px30 use a different ip block to handle
one-time-programmable memory, so add a misc driver for it as well.
