Warn if the conditions to enter or exit DC5 are not satisfied such as support for runtime PM, state of power well, CSR loading etc. v2: Removed camelcase in functions and variables. v3: Do some minimal check to assert if CSR program is not loaded. v4: 1] Used an appropriate function lookup_power_well() to identify power well, instead of using a magic number which can change in future. 2] Split the conditions further in assert_can_enable_DC5() and added more checks. 3] Removed all WARNs from assert_can_disable_DC5 as they were unnecessary and added two new ones. 4] Changed variable names as updated in earlier patches. v5: 1] Change lookup_power_well function to take an int power well id. 2] Define a new intel_display_power_well_is_enabled helper function to check whether a particular power well is enabled. 3] Use CSR-related mutex in assert_csr_loaded function. v6: Remove use of dc5_enabled variable as it's no longer needed. v7: 1] Rebase to latest. 2] Move all DC5-related functions from intel_display.c to intel_runtime_pm.c. v8: After adding dmc ver 1.0 support rebased on top of nightly. (Animesh) v9: Modified below changes based on review comments from Imre. - Moved intel_display_power_well_is_enabled() to intel_runtime_pm.c. - Removed mutex lock from assert_csr_loaded().
