mei: late_bind: Fix -Wincompatible-function-pointer-types-strict

When building with -Wincompatible-function-pointer-types-strict, a
warning designed to catch kernel control flow integrity (kCFI) issues at
build time, there is an instance in the new mei late binding code
originating from the type parameter of mei_lb_push_payload():

  drivers/misc/mei/mei_lb.c:211:18: error: incompatible function pointer types initializing 'int (*)(struct device *, u32, u32, const void *, size_t)' (aka 'int (*)(struct device *, unsigned int, unsigned int, const void *, unsigned long)') with an expression of type 'int (struct device *, enum intel_lb_type, u32, const void *, size_t)' (aka 'int (struct device *, enum intel_lb_type, unsigned int, const void *, unsigned long)') [-Werror,-Wincompatible-function-pointer-types-strict]
    211 |         .push_payload = mei_lb_push_payload,
        |                         ^~~~~~~~~~~~~~~~~~~

While 'unsigned int' and 'enum intel_lb_type' are ABI compatible, hence
no regular warning from -Wincompatible-function-pointer-types, the
mismatch will trigger a kCFI violation when mei_lb_push_payload() is
called indirectly.

Update the type parameter of mei_lb_push_payload() to be 'u32' to match
the prototype in 'struct intel_lb_component_ops', clearing up the
warning and kCFI violation.
