Use the msm_kms_init_vm() function to allocate memory manager instead of
hand-coding a copy of it. Although MDP4 platforms don't have MDSS
device, it's still safe to use the function as all MDP4 devices have
IOMMU and the parent of the MDP4 is the root SoC device.

As we've dropped no-IOMMU support, there is no reason to specially
handle the no-IOMMU case inside msm_iommu_new(). Make it return -ENODEV
if there is no IOMMU (instead of returning NULL) and simplify all
calling sites accordingly.

With the switch to GPUVM the msm driver no longer supports the no-IOMMU
configurations (even without the actual GPU). Return an error in case we
face the lack of the IOMMU.

When executing modinfo null_blk, there is an error in the description
of module parameter mbps, and the output information of cache_size is
incomplete.The output of modinfo before and after applying this patch
is as follows:
Before:
[...]
parm: cache_size:ulong
[...]
parm: mbps:Cache size in MiB for memory-backed device.
Default: 0 (none) (uint)
[...]
After:
[...]
parm: cache_size:Cache size in MiB for memory-backed device.
Default: 0 (none) (ulong)
[...]
parm: mbps:Limit maximum bandwidth (in MiB/s).
Default: 0 (no limit) (uint)
[...]
Fixes: 058efe000b31 ("null_blk: add module parameters for 4 options")

MAX_TAG_SIZE was 0x1a8 and it may be truncated in the "bi->metadata_size
= ic->tag_size" assignment. We need to limit it to 255.

This driver implements both the determine_rate() and round_rate() clk
ops, and the round_rate() clk ops is deprecated. When both are defined,
clk_core_determine_round_nolock() from the clk core will only use the
determine_rate() clk ops. Also all clk drivers that directly calls
fixed-factor's round_rate() have been migrated over to determine_rate().
So let's remove the round_rate() clk ops.
