hrtimers: Replace hrtimer_clock_to_base_table with switch-case
Clang and GCC complain about overlapped initialisers in the
hrtimer_clock_to_base_table definition. With `make W=1` and CONFIG_WERROR=y
(which is default nowadays) this breaks the build:
CC kernel/time/hrtimer.o
kernel/time/hrtimer.c:124:21: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
124 | [CLOCK_REALTIME] = HRTIMER_BASE_REALTIME,
kernel/time/hrtimer.c:122:27: note: previous initialization is here
122 | [0 ... MAX_CLOCKS - 1] = HRTIMER_MAX_CLOCK_BASES,
(and similar for CLOCK_MONOTONIC, CLOCK_BOOTTIME, and CLOCK_TAI).
hrtimer_clockid_to_base(), which uses the table, is only used in
__hrtimer_init(), which is not a hotpath.
Therefore replace the table lookup with a switch case in
hrtimer_clockid_to_base() to avoid this warning.
