Revert "libcamera: rkisp1: Eliminate hard-coded resizer limits"

This reverts commit e85c7ddd38ce8456ab01c2a73baf9e788f6a462e.

Linux kernel predating 6.4 (specifically commit 7cfb35d3a800 ("media:
rkisp1: Implement ENUM_FRAMESIZES") do not have the ioctl in rkisp1
driver required to dynamically query the resizer limits.

Because of that, maxResolution and minResolution are both {0, 0}
(default value for Size objects) which means filterSensorResolution()
will create an entry for the sensor in sensorSizesMap_ but because the
sensor resolution cannot fit inside the min and max resolution of the
rkisp1, no size is put into this entry in sensorSizesMap_.
On the next call to filterSensorResolution(),
sensorSizesMap_.find(sensor) will return the entry but when attempting
to call back() on iter->second, it'll trigger an assert because the size
array is empty.

Linux kernel 6.1 is supported until December 2027, so it seems premature
to get rid of those hard-coded resizer limits before this happens.

Let's restore the hard-coded resizer limits as fallbacks, actual limits
are still queried from the driver on recent enough kernels.
