media: atomisp: get rid of an iomem abstraction layer
The hive_isp_css_custom_host_hrt.h code, together with atomisp_helper.h, provides an abstraction layer for some functions inside atomisp_compat_css20.c and atomisp_cmd.c. There's no good reason for that. In a matter of fact, after removing the abstraction, the code looked a lot cleaner and easier to understand. So, get rid of them. While here, get rid also of the udelay(1) abstraction code. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
