Replace infracfg clk ID with upstream linux version.
The same format is used here with the factor first, then mux and then
gates.
To correctly reference the gates in clk_gate function, define the
gates_offs value in clk_tree now that they are at an offset from mux and
factor.

Now that we can have advanced parent handling for mux, we can drop
spurious topckgen 1/1 factor. This is in preparation to make the clk
ID match the ID in upstream include for mt7986.
Drop the factor entry from mt7986-clk.h and reference to them in
mt7981.dtsi. Muxes and gates are updated to reference the apmixed clk
following how it's done in upstream kernel linux. Add relevant clk type
flag in clk_tree for apmixed.

Some chips like Exynos4412 have fixed internal CIU clock divider.
Instead of reading it from non-standard "div" dts property, store its
value in the driver internally, in static chip data associated with
corresponding compatible. This makes it possible to avoid using
host->div for storing it, so the latter can be removed safely. Also
create a helper function called exynos_dwmmc_get_ciu_div() for getting
the current div value: in case the fixed div is provided in the chip
data it will be used, otherwise the current div value is being read from
CLKSEL register.
The insights for this change were taken from dw_mmc-exynos.c driver in
Linux kernel.

Replace fifoth_val property with its fifo-depth counterpart in all DW
MMC drivers. fifo-depth is a common property used in upstream Linux
kernel. The FIFOTH register value will be calculated using fifo-depth
value in DW MMC core (dw_mmc.c). This change reduces code duplication in
platform drivers, and pulls common FIFOTH register value calculation
into core dw_mmc driver where it belongs.

Some DW MMC blocks (e.g. those on modern Exynos chips) support 64-bit
DMA addressing mode. 64-bit DW MMC variants differ from their 32-bit
counterparts:
- the register layout is a bit different (because there are additional
IDMAC registers present for storing upper part of 64-bit addresses)
- DMA descriptor structure is bigger and different from 32-bit one
Introduce all necessary changes to enable support for 64-bit DMA capable
DW MMC blocks. Next changes were made:
1. Check which DMA address mode is supported in current IP-core
version. HCON register (bit 27) indicates whether it's 32-bit or
64-bit addressing. Add boolean .dma_64bit_address field to struct
dwmci_host and store the result there. dwmci_init_dma() function is
introduced for doing so, which is called on driver's init.
2. Add 64-bit DMA descriptor (struct dwmci_idmac64) and use it in
dwmci_prepare_desc() in case if .dma_64bit_address field is true.
A new dwmci_set_idma_desc64() function was added for populating that
descriptor.
3. Add registers for 64-bit DMA capable blocks. To make the access to
IDMAC registers universal between 32-bit / 64-bit cases, a new
struct dwmci_idmac_regs (and corresponding host->regs field) was
introduced, which abstracts the hardware by being set to
appropriate offset constants on init. All direct calls to IDMAC
registers were correspondingly replaced by accessing host->regs.
4. Allocate and use 64-bit DMA descriptors buffer in case when IDMAC
is 64-bit capable. Extract all the code (except for the IDMAC
descriptors buffer allocation) from dwmci_send_cmd() to
dwmci_send_cmd_common(), so that it's possible to keep IDMAC
buffer (either 32-bit or 64-bit) on stack during send_cmd routine.
The insights for this implementation were taken from Linux kernel DW MMC
driver.

bootstage_get_size() returns the total size of the data structure
including associated records.
When copying from gd->bootstage, only the allocation size of gd->bootstage
must be used. Otherwise too much memory is copied.
This bug caused no harm so far because gd->new_bootstage is always
large enough and reading beyond the allocation length of gd->bootstage
caused no problem due to the U-Boot memory layout.
Fix by using the correct size and perform the initial copy directly
in bootstage_relocate() to have the whole relocation process in the
same function.
