habanalabs: make functions static or declare them
This patch fixes the below sparse warnings by either making the functions static or by adding a declaration in the relevant header file. In addition, the patch removes goya_mmap completely as it doesn't add any additional benefit. Fixes the following sparse warnings: drivers/misc/habanalabs/habanalabs_drv.c:24:1: warning: symbol 'hl_devs_idr' was not declared. Should it be static? drivers/misc/habanalabs/habanalabs_drv.c:25:1: warning: symbol 'hl_devs_idr_lock' was not declared.
