Cache up to 4 kiB entries. 4 kiB is the default block size on ext4, yet
the underlying block layer devices usually report support for 512B . In
most cases, the 512B support is emulated (ie. SD cards, SSDs, USB sticks
etc.) and the real block size of those devices is much bigger.
To avoid performance degradation with such devices and FS setup, bump
the maximum cache entry size to 4 kiB.

If _debug_uart_putc() is called before _debug_uart_init(), the
ns16550 debug uart driver hangs in a tight loop waiting for the
tx FIFO to get empty.
As this can happen via a printf sneaking in before the port calls
debug_uart_init(), introduce a config option to ignore characters
before the debug uart is initialized.
This is done by reading the baudrate divisor and aborting if is zero.
The Kconfig option is required as reading the baudrate divisor does
not seem to work for all ns16500 compatibles (which is why the last
attempt on this has been reverted in 1a67969a99).
Tested on socfpga_cyclone5_socrates.

The mmc_select_mode_and_width() function can be called while the card
is in HS200/HS400 mode and can be used to downgrade the card to lower
mode, e.g. HS. This is used for example by mmc_boot_part_access_chk()
which cannot access the card in HS200/HS400 mode and which is in turn
called by saveenv if env is in the MMC.
In such case, forcing the card clock to legacy frequency cannot work.
Instead, the card must be switched to HS mode first, from which it can
then be reprogrammed as needed.
However, this procedure needs additional code changes, since the current
implementation checks whether the card correctly switched to HS mode in
mmc_set_card_speed(). The check only expects that the card will be going
to HS mode from lower modes, not from higher modes, hence add a parameter
which indicates that the HS200/HS400 to HS downgrade is happening. This
makes the code send the switch command first, reconfigure the controller
next and finally perform the EXT_CSD readback check. The last two steps
cannot be done in reverse order as the card is already in HS mode when
the clock are being switched on the controller side.

This reverts commit a7f4b4b344.
As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:
1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)
2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).
3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).
As we are very close to release - please revert this commit.

The current pinctrl driver for the RK3399 has a range of qulity issues.
E.g. it only implements the .set_state_simple() callback, it
does not parse the available pinctrl information from the DTS
(instead uses hardcoded values), is not flexible enough to cover
devices without 'interrupt' field in the DTS (e.g. PWM),
is not written generic enough to make code reusable among other
rockchip SoCs...
This patch addresses these issues by reimplementing the whole driver
from scratch using the .set_state() callback.
The new implementation covers all featurese of the old code
(i.e. it supports pinmuxing and pullup/pulldown configuration).
This patch has been tested on a RK3399-Q7 SoM (Puma).
