MLK-20790-2 rpmsg: imx_rpmsg: use unregister/register virtio device instead of rpmsg device

Currently, issue RPMSG_NS_DESTROY before kick off ready notification to
m4 to let m4 side go through all the stale message in vring buffer without
doing anything after m4 reset, that's not good enough. The better way is to
clear vring buffer after m4 reset, thus everything will be done as the
first time of kernel/m4 bootup. So unregister/register virtio device
instead of rpmsg device if m4 partition reset.

MLK-20653 rpmsg: virtio_rpmsg_bus: fix unexpected huge vmap mappings

If RPMSG dma memory allocate from per-device mem pool by calling .dma_alloc_coherent(),
the size is bigger than 2M bytes and alignment with 2M (PMD_SIZE), then kernel dump by
calling .vmalloc_to_page().

Since per-device dma pool do vmap mappings by __ioremap(), __ioremap() might use
the hugepage mapping, which in turn will cause the vmalloc_page failed to return
the correct page due to the PTE not setup.

For exp, when reserve 8M bytes per-device dma mem pool, __ioremap() will use hugepage
mapping:
 __ioremap
ioremap_page_range
ioremap_pud_range
ioremap_pmd_range
pmd_set_huge(pmd, phys_addr + addr, prot)

Commit:029c54b09599 ("mm/vmalloc.c: huge-vmap: fail gracefully on unexpected huge
vmap mapping") ensure that vmalloc_to_page() does not go off into the weeds trying
to dereference huge PUDs or PMDs as table entries:
rpmsg_sg_init ->
vmalloc_to_page->
WARN_ON_ONCE(pmd_bad(*pmd));

In generally, .dma_alloc_coherent() allocate memory from CMA pool/DMA pool/atomic_pool,
or swiotlb slabs pool, the virt address mapping to physical address should be lineal,
so for the rpmsg scatterlist initialization can use pfn to find the page to avoid to
call .vmalloc_to_page().

The PWM in i.MX8qxp MIPI subsystem needs to use the
'32k' clock to work properly.  This patch gets this
clock in the PWM driver and uses it if it is supplied.

MLK-18627 pwm: imx: Add clk_ipg for imx8qm

As part of converting the imx pwm driver to an atomic apply function the
code handling ipg clock was dropped. Add it back because on imx8qm it is
indeed required.

This fixes the same issue as imx_4.9.y commit

MLK-20958-2 imx8: Replace SC_R_LAST with SC_R_NONE in DTB

We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

MLK-21057 serial: imx: Restore proper init of shadow registers

Upstream commit 3a0ab62f43de ("serial: imx: implement shadow registers
for UCRx and UFCR") made the imx_uart_readl/writel functions use a
"cache" to avoid reads/writers to hardware for some registers.

Those values need to be initialized once at probe time using real reads
from hardware; using imx_uart_readl for this is obviously non-functional

Fixes: 372312842fe7 ("tty: serial: imx: use imx_uart_writel() and imx_uart_readl()")

This is required for imx8mq to boot and likely fixes other things.
