arm64: dts: qcom: glymur: Add missing USB clock, power and bandwidth votes

The four USB3 controller nodes on Glymur (usb_0, usb_1, usb_2, usb_mp)
are missing three property groups that Glymur's own usb_hs node at
a200000 already carries, and that Hamoa (x1e80100) carries on all five
of its USB controllers:

  - assigned-clocks / assigned-clock-rates
  - required-opps
  - interconnects / interconnect-names

Without required-opps the controllers place no performance state vote
on their power domain. Measured on an Asus Zenbook A16 (UX3607OA) with
a SuperSpeed device enumerated, CX aggregates to SVS while the
controllers run their master clock at 200 MHz:

  $ grep -E "^cx " /sys/kernel/debug/pm_genpd/pm_genpd_summary
  cx    on    128

  $ grep "usb30.*master_clk " /sys/kernel/debug/clk/clk_summary
  gcc_usb30_sec_master_clk   ...  200000000
  gcc_usb30_prim_master_clk  ...  200000000
  gcc_usb30_mp_master_clk    ...  200000000

128 is RPMH_REGULATOR_LEVEL_SVS; rpmhpd_opp_nom is 256. With this
patch applied the same measurement reads 256 while a controller is
active.

Without interconnects, dwc3_qcom_interconnect_init() silently does
nothing: of_icc_get() returns NULL rather than an error pointer for a
device without the property, so probe succeeds and icc_set_bw() on a
NULL path is a no-op. No USB-DDR bandwidth is ever requested.

Without assigned-clock-rates nothing programs the master clock RCG,
which keeps whatever the bootloader left behind. On this machine that
happens to be the correct 200 MHz, but ftbl_gcc_usb30_mp_master_clk_src
also allows 66.67 and 133.33 MHz, neither of which sustains SuperSpeed.

Add all three groups to the four nodes, mirroring usb_hs. The
interconnect paths follow the provider layout in
drivers/interconnect/qcom/glymur.c: usb_0/usb_1 sit on aggre4_noc,
usb_mp on aggre3_noc and usb_2 on aggre2_noc.
