44d0ed23e5 media: i2c: alvium: fix alvium_get_fw_version()
Instead of reading device_fw reg as multiple regs let's read the entire
64bit reg using one i2c read and use bit masks and bit shifts to get fw
info.

d7f686d8c5 media: i2c: alvium: remove the fr field of the alvium_dev structure
The fr (frame rate) field of the alvium_dev structure is
only used to pass result from alvium_set_frame_interval() to
alvium_set_frame_rate() that writes this info into the hw reg.
Replace it with a function parameter.
