The generic code in common/spl/spl.c allows TPL/SPL banners to be
silenced by unsetting CONFIG_TPL_BANNER_PRINT or CONFIG_SPL_BANNER_PRINT
respectively. However, arch/arm/mach-rockchip/tpl.c prints this banner
unconditionally.
Fix the rockchip-specific tpl.c so that the TPL banner depends on
CONFIG_TPL_BANNER_PRINT in the same way as the generic code.

Instead, initialise the debug UART and print the TPL banner only if both

If secure mode is off (default, or -machine virt,secure=off) at qemu,
it will provide dtb with two flash memory banks:

If secure mode is on, on the other hand, qemu provides dtb with 1 bank:
flash@0 {
bank-width = <0x4>;
reg = <0x0 0x4000000 0x0 0x4000000>;

The TI AM654x EVM base board and the associated daughtercards have on-

board detection infrastructure introduced earlier to do the following:
1) Parse the AM654x EVM base board EEPROM and populate items like board
name and MAC addresses into the TI common EEPROM data structure
residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
presence signals via an I2C-based GPIO expander. Then, if such a
card is found, parse the data such as additional Ethernet MAC
addresses from its on-board EEPROM and populate into U-Boot
accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
containing a list of daugherboard-specific DTB overlays based on
daughercards found.

The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the
wkup_i2c0 bus at address 0x38 that is used to detect the presence of
daughter cards. Add a respective DTS description of this expander
to enable its use.

To enable the use of an EEPROM-based board detection scheme we need to
be able to access the I2C bus associated with the EEPROMs across all
3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go
ahead and add/update the wkup_i2c0 peripheral module DTS definitions
and its associated pinmux node accordingly.
