[DRIVERS][RK3399] fix handling of rgmii modes and delays
This commit:
- adds handling of the rgmii-id mode which disables both external delays in the gmac
- fixes the rk3399_gmac_set_to_rgmii function which should disable RX delay and/or TX delay on the gmac if they are set to -1 (as the rk3588 function does for example); instead, currently, the function still enables the delays and writes -1 (11111111) as a delay value, which is the max value
- simplify the switch/case in the probe function which currently contains some duplicated code

[C31][DTS] fix ethernet delays
The current ethernet configuration sets delays in both MAC and PHY. This requires to alter the drivers to allow forcing both delays, which is unnecessary.
This commit sets mode to rgmii-id and sets internal delays to tx=2.75ns and rx=1.75ns. How these values were calculated: the RK3399 gmac is capable of a ~5ns delay. The rx_delay and tx_delay properties can have values 0-100, so one step is ~0.05ns.

[CMD] Change getline function's behavior for fix input size
Usually the number of items of a single menu in seco_config command is less than ten but in some cases this number increases and an char input is replaced with a string input. In order to obtain the same user experience in both cases (selection from a list less of ten and more of nine) a check on this number has been introduced and a number of max characher to expect in input is passed to the getline function. With the commit also the getline function has been changed in order to receive as argument this number of maximum character to read.

[DRIVERS] gpio_watchdog: use __udelay() instead of udelay() in hw_watchdog_reset
The hw_watchdog_reset function calls mdelay which calls udelay which in turn calls hw_watchdog_reset. So to eliminate this circular dependency, the __mdelay function has been introduced which calls directly __udelay without resetting the watchdog as udelay did.

[DRIVERS] rockchip_display: Fix getting CRTC ID
Different SoCs in its dts have different VOP node structure rk3568 in vop node has both ports and port nodes and port has reg property, but rk3399 has only port node without reg property. To set right value in the register that selects vop little or big, in case of rk3399 we need to go up to remote endpoint node to get CRTC ID from its reg property, otherwise function return 0 and there is no possibility to use VOP little.

[C31] [DTS] GMAC: Add PHY internal delay and FIFO depth properties
Set FIFO depth to DP83867_PHYCR_FIFO_DEPTH_8_B_NIB as PHY Control Register (PHYCR), at Address 0x0010, bit [15:14] set: => mdio read ethernet@fe300000 9.0x0010 Reading from bus ethernet@fe300000 PHY at address 9: 9.16 - 0xc040 TX FIFO Depth: 11 = 8 bytes Set ti,tx-internal-delay and ti,rx-internal-delay to DP83867_RGMIIDCTL_1_NS as in U-Boot stable version.
it would be better to pass these properties using the child node phy@9 passed to the gmac node as value of the phy-handle property, but the driver PHY is not brought into the driver model, that's why DP83867 won't find these properties in the phy node, so keep those properties in gmac node
