ramips: add proper system clock and reset driver support for legacy SoCs

This series of upstream patches properly implement a clock and reset driver for old ralink SoCs[1]. And it includes some related fixes[2] and improvements[3][4]. All patches have been merged into linux-next. They will be part of upcoming Linux 6.5. In order to switch to the new system controller driver, all clocks and resets properties in SoC dtsi have been updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the kernel config files.

 Subject: [PATCH 1/9] dt-bindings: clock: add mtmips SoCs system controller
 Adds device tree binding documentation for system controller node present
 in Mediatek MIPS and Ralink SOCs. This node is a clock and reset provider
 for the rest of the world. This covers RT2880, RT3050, RT3052, RT3350,
 RT3883, RT5350, MT7620, MT7628 and MT7688 SoCs.

 +description: |
 +  MediaTek MIPS and Ralink SoCs provides a system controller to allow
 +  to access to system control registers. These registers include clock
 +  and reset related ones so this node is both clock and reset provider
 +  for the rest of the world.
 +
 +  These SoCs have an XTAL from where the cpu clock is
 +  provided as well as derived clocks for the bus and the peripherals.

 Subject: [PATCH 6/9] mips: ralink: mt7620: remove clock related code
 A proper clock driver for ralink SoCs has been added. Hence there is no
 need to have clock related code in 'arch/mips/ralink' folder anymore.
 Since this is the last clock related code removal, remove also remaining
 prototypes in 'common.h' header file.

 Subject: [PATCH 7/9] mips: ralink: remove reset related code
 A proper clock driver for ralink SoCs has been added. This driver is also
 a reset provider for the SoC. Hence there is no need to have reset related
 code in 'arch/mips/ralink' folder anymore. The only code that remains is
 the one related with mips_reboot_setup where a PCI reset is performed.
 We maintain this because I cannot test old ralink board with PCI to be
 sure all works if we remove also this code.

 Subject: [PATCH 8/9] mips: ralink: get cpu rate from new driver code
 At very early stage on boot, there is a need to set 'mips_hpt_frequency'.
 This timer frequency is a half of the CPU frequency. To get clocks properly
 set we need to call to 'of_clk_init()' and properly get cpu clock frequency
 afterwards. Depending on the SoC, CPU clock index and compatible differs, so
 use them to get the proper clock frm the clock provider. Hence, adapt code
 to be aligned with new clock driver.

 Subject: [PATCH] mips: ralink: introduce commonly used remap node function
 The ralink_of_remap() function is repeated several times on SoC specific
 source files. They have the same structure, but just differ in compatible
 strings. In order to make commonly use of these codes, this patch
 introduces a newly designed mtmips_of_remap_node() function to match and
 remap all supported system controller and memory controller nodes.
 Build and run tested on MT7620 and MT7628.

 Set ret to the return value of clk_hw_register_fixed_rate() using the
 PTR_ERR() macro, which ensures ret is not used uninitialized, clearing
 up the warning.

 Subject: mips: ralink: match all supported system controller compatible
 strings
 Recently, A new clock and reset controller driver has been introduced to
 the ralink mips target[1]. It provides proper system control and adds more
 SoC specific compatible strings. In order to better initialize CPUs, this
 patch removes the outdated "ralink,mt7620a-sysc" and add all dt-binding
 documented compatible strings to the system controller match table.
