tee: fix compiler warning in tee_shm_register()
[ Upstream commit eccd7439709810127563e7e3e49b8b44c7b2791d ]
Include <linux/uaccess.h> to avoid the warning:
drivers/tee/tee_shm.c: In function 'tee_shm_register':
>> drivers/tee/tee_shm.c:242:14: error: implicit declaration of function 'access_ok' [-Werror=implicit-function-declaration]
242 | if (!access_ok((void __user *)addr, length))
| ^~~~~~~~~
cc1: some warnings being treated as errors
Fixes: 573ae4f13f63 ("tee: add overflow check in register_shm_helper()")
