bfb1b99802 media: mediatek: vcodec: avoid -Wcast-function-type-strict warning
The ipi handler here tries hard to maintain const-ness of its argument,
but by doing that causes a warning about function type casts:

drivers/media/platform/mediatek/vcodec/common/mtk_vcodec_fw_vpu.c:38:32: error: cast from 'mtk_vcodec_ipi_handler' (aka 'void (*)(void *, unsigned int, void *)') to 'ipi_handler_t' (aka 'void (*)(const void *, unsigned int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
   38 |         ipi_handler_t handler_const = (ipi_handler_t)handler;
      |                                       ^~~~~~~~~~~~~~~~~~~~~~

Remove the hack and just use a non-const argument.

56c0ac05a3 media: mediatek: vcodec: using encoder device to alloc/free encoder memory
Need to use encoder device to allocate/free encoder memory when calling
mtk_vcodec_mem_alloc/mtk_vcodec_mem_free, or leading to below crash log
when test encoder with decoder device.
