soc: driver updates for 6.17

Changes are all over the place, but very little sticks out as
 noteworthy.
 
 There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
 I/O chip, along with hooking it up to the pinctrl and clk frameworks.
 
 The reset controller and memory subsystems have mainly small updates,
 but there are two new reset drivers for the K230 and VC1800B SoCs,
 and new memory driver support for Tegra264.
 
 The ARM SMCCC and SCMI firmware drivers gain a few more features that
 should help them be supported across more environments. Similarly,
 the SoC specific firmware on Tegra and Qualcomm get minor enhancements
 and chip support.
 
 In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
 overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
 grow to support more chips, while the Hisilicon, Mediatek and Renesas
 drivers see mostly janitorial fixes.

+ * The reset management module in the K230 SoC provides reset time control
+ * registers. For RST_TYPE_CPU0, RST_TYPE_CPU1 and RST_TYPE_SW_DONE, the period

+ * up to 255 * 0.25 = 63.75 µs. For RST_TYPE_FLUSH, the reset bit is
+ * automatically cleared by hardware when flush completes.
+ *
+ * Although this driver does not configure the reset time registers, delays have
+ * been added to the assert, deassert, and reset operations to cover the maximum
+ * reset time. Some reset types include done bits whose toggle does not
+ * unambiguously signal whether hardware reset removal or clock-stop period
