This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe") but applied to a whole pile of drivers. This batch converts
the drivers that appeared to have been added after kernel 5.4.

For Meson8 and Meson8b SoCs the vendor driver follows the following
pattern:
- for eMMC and SD cards in .set_pdma it sets:
pdma->rxfifo_manual_flush = 1;
- for SDIO cards in .set_pdma it sets:
pdma->rxfifo_manual_flush = 0;
- before syncing the DMA read buffer is sets:
pdma->rxfifo_manual_flush |= 0x02;
Set the second bit of MESON_SDHC_PDMA_RXFIFO_MANUAL_FLUSH without
clearing the first bit before syncing the DMA read buffer. This fixes a
problem where Meson8 and Meson8b SoCs would read random garbage from SD
cards. It is not clear why it worked for eMMC cards. This manifested in
the following errors when plugging in an SD card:
unrecognised SCR structure version <random number>

For an x86_64 allmodconfig build Stephen reports that building
meson-mx-sdhc-clkc.o warns that MODULE_LICENSE is missing and when
linking meson_mx_sdhc_register_clkc cannot be found.
Compile the MMC controller driver together with the build-in clock
controller driver into one module rather than using two separate
modules to fix these issues.
