Building HWPM with Linux v5.14 currently fails because the arguments
passed to the dma_buf_vmap and dma_buf_vunmap functions is incorrect.
The arguments passed to the dma_buf_vmap and dma_buf_vunmap functions
were actually updated in Linux kernel version v5.11 and not v5.15. So
correct the kernel version in the HWPM driver so that the correct
version of the APIs are used for Linux kernels v5.11+.
Finally, drop the kernel version check around the inclusion of module.h
and the import of the module namespace because this is not necessary.

- Create tegra_hwpm_element_enable() instead of directly using
perfmon_enable() HAL. This will allow us to expand
tegra_hwpm_element_enable in future.
- Update log messages in ip structure init code and floorsweep info
function.
- It is possible that IP instances and elements to have 0 start range
address. So, modify check for available elements to use range end
instead.
- Use tegra_hwpm_fake_readl() and tegra_hwpm_fake_writel() macros
instead of fake_readl() and fake_write() functions. That way we have
similar implementation of IO functions and macros can be used across
OSes.
- Check that reserve perfmon function is invoked only for HWPM
components. This check will be useful for expansion in types of
components in the future.
- Clean up and rearrange tegra_hwpm_regops_readl_impl() and
tegra_hwpm_regops_writel_impl() to have designated code corresponding to
the element type.
- Currently, device open and release functions are incorrectly using
clock enable/disable functions instead of using HALs. Correct open and
close functions to use lock HALs.
- Currently, tegra_hwpm_update_mem_bytes() doesn't validate mem_mgmt
structure allocation before accessing mem_bytes_kernel pointer. This can
lead to kernel crash. Update tegra_hwpm_update_mem_bytes() to return
error if mem_mgmt structure s not allocated.

Currently on TOT, stream buffer map functions results in kernel crash.
The kernel crash is an effect of incorrect conditions in the mapping
function. Fix the code logic to use correct kernel version conditions to
use appropriate DMA buffer structures.

Kernel version beyond 5.10 introduces dma_buf_map structure (called
iosys_map in later versions). Kernel virtual address corresponding to a
dma_buf is stored in the dma_buf_map structure.
- This patch updates memory management function to use correct mem bytes
buffer kernel virtual address stored in the corresponding dma_buf_map
structure.
- Use dma_buf_map structure pointer to unmap kernel virtual address.
- During release, poll mem bytes buffer with finite timeout value.
- Add description for use of dma_set_mask_and_coherent.
