media: imx-mipi-csis: Rename register macros to match reference manual

The CSIS driver uses register macro names that do not match the
reference manual of the i.MX7[DS] and i.MX8M[MNP] SoCs in which the CSIS
is integrated. Rename them to match the documentation, making the code
easier to read alongside the reference manuals.

One of the misnamed register fields is MIPI_CSIS_INT_SRC_ERR_UNKNOWN,
which led to the corresponding event being logged as "Unknown Error".
The correct register field name is MIPI_CSIS_INT_SRC_ERR_ID, documented
as "Unknown ID error". Update the event description accordingly.

While at it, also replace a few *_OFFSET macros with parametric macros
for consistency, and add the missing MIPI_CSIS_ISP_RESOL_VRESOL and
MIPI_CSIS_ISP_RESOL_HRESOL register field macros.

No functional change intended.
