Subject: [PATCH v2 1/2] regmap: mdio: Fix regmap_bus pointer constness

A const qualifier was omitted in the declaration of the regmap_bus
pointer, resulting in the following errors:

drivers/base/regmap/regmap-mdio.c: In function ‘__regmap_init_mdio’:
drivers/base/regmap/regmap-mdio.c:87:7: warning: assignment discards
‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
87 | bus = &regmap_mdio_c22_bus;
| ^
drivers/base/regmap/regmap-mdio.c:89:7: warning: assignment discards
‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
89 | bus = &regmap_mdio_c45_bus;
| ^

Fix this by ensuring the pointer has the same qualifiers as the assigned
values.
