media: ti-vpe: cal: avoid FIELD_GET assertion 

FIELD_GET() must only be used with a mask that is a compile-time
constant:

drivers/media/platform/ti-vpe/cal.h: In function 'cal_read_field':
include/linux/compiler_types.h:320:38: error: call to '__compiletime_assert_247' declared with attribute error: FIELD_GET: mask is not constant
include/linux/bitfield.h:46:3: note: in expansion of macro 'BUILD_BUG_ON_MSG'
   46 |   BUILD_BUG_ON_MSG(!__builtin_constant_p(_mask),  \
      |   ^~~~~~~~~~~~~~~~
drivers/media/platform/ti-vpe/cal.h:220:9: note: in expansion of macro 'FIELD_GET'
  220 |  return FIELD_GET(mask, cal_read(cal, offset));
      |         ^~~~~~~~~

The problem here is that the function is not always inlined. Mark it
__always_inline to avoid the problem.
